I’m a dermatologist. I’m supposed to say there is no amount of safe sun exposure.

But I won’t, because that’s a lie.

The attached shows how much sun is safe in different cities at different times of year.

What do I mean by ‘safe’?

I mean this: UV causes DNA damage and skin cancer.

But, shockingly, your body repairs that damage. As long as the damage doesn’t outpace repair and start accumulating it shouldn't increase your risk of skin cancer.

Data just came out that tells us how much UV you can get without damage accumulating.

They took the people most susceptible to DNA damage from UV and exposed them to UV, then did skin biopsies to measure the damage, then more skin biopsies to measure the repair, and repeated it daily for 4 days.

At 1.6 ‘Standard Erythemal Dose’ (SED) there was no accumulation of damage.

So, the attached charts show how much sun it takes to get 1 SED in different cities at different times of the year at different times of day.

And there are extra safety margins built in. It assumes a perfectly clear day with zero air pollution and that the sun is hitting your skin perpendicularly. Unless you’re laying flat, most sun is hitting you at an angle, which isn’t nearly as intense.

But a bigger question you might be asking is ‘Why would a dermatologist be telling you to get sun in the first place?’

Because getting sun reduces your risk of death.

Mostly by reducing your risk of heart attacks and strokes. That is very well proven.

But it’s also very likely that sun exposure reduces your risk of autoimmune disease, dementia, cancer and depression. It’s just not as well proven as the protection against heart attacks and strokes.

And before you reply and say ‘just take vitamin D!’, know that it has been ROBUSTLY proven that vitamin D has little (if any) benefit for preventing any of the above. Vitamin D is mostly useful as a marker of if you’re getting enough sun.

What do I do myself and what do I tell my patients?

Get as much unprotected sun exposure as you can without getting a burn.

That’s my GUESS as to what has the best risk/benefit ratio. Dying of skin cancer is actually really rare, especially when compared to the risk of heart attacks, strokes, autoimmune disease, dementia and other cancers.

But I’ll admit it’s not for sure best to get as much sun as possible, since sun does increase the risk of skin cancer and it might be the case the benefits plateau at a low level.

So, if you’re really worried about skin cancer stick to the charts.

The best science I can find says that amount won’t cause skin cancer.

The takeaway?

Sun is good for you, just don’t get a burn.

@MehtabKarta Makes sense bc ai lifted the floor, I'm guessing. Now great is good, good is average, average is bad 👍🏽

Lionel Messi was given HGH in his adolensce and became the greatest player of all time. If he didnt get this, he would have been 5'3ish~

Not doing this for your children will be putting them at a disadvantage

@Seanfrank Survivorship bias is real. It's very easy to say that after being successful, and it's deserved. Things change when you build positive momentum, it's much easier to think and be positive.

Funny how when @ZohranKMamdani was telling New Yorkers to lower their AC his wife Rama Duwaji was boarding a flight to party in Mallorca

Reminder that I can’t tag her because she deleted her account after her insanely offensive tweets were discovered

The longer you postpone the life you want, the more responsibilities accumulate, optionality shrinks, and what once felt temporary becomes your permanent life.

surprised more people aren't doing something like this

Codex now creates a "newspaper" for me every morning

Unread messages, calendar, surf report, news

Anything I can do to stay off my phone until later in the day is a priority

@alecsandrull Absolutely had this thought until there was 1 purchase attribution anywhere on GA after 2 months of legit spend ($5k) I wanted it to work so bad, it makes so much sense *in theory* but not backed by the slightest bit of evidence for me (older woman apparel brand)

The 5 facebook group types printing the most money in ecom:

1. Women's health groups (600K+ members) - "Natural Remedies." "Menopause Support." "Women's Health After 40." A woman posts "does anyone know something for knee pain" at 11pm. 14 strangers reply with product links within an hour. She buys 2-3 before bed. 40 lurkers with the same problem buy too. $200-500 generated per thread. 50-200 threads per day in one group

2. Pet parent groups (400K+ members) - "Dog Moms." "Anxious Dog Support." "Golden Retriever Lovers." "My dog won't stop scratching" generates 30 product links in 60 minutes. $120 AOV. 40%+ subscribe. The guilt of canceling a pet supplement is the retention mechanism not the product

3. Chronic pain groups (200K+ members) - "Fibromyalgia Warriors." "Living With Arthritis." Most underserved buyer in ecom. She's tried everything. When she finds something that works she never switches. Subscription churn under 8%. LTV: 12-18 months. Zero operators target her

4. New parent groups (300K+ members) - "First Time Moms." "Breastfeeding Help." Active 24 hours because babies don't have schedules. "My baby won't sleep" at 3am generates 20 product links by 3:30am from other moms who are also awake with their babies

5. Cooking and recipe groups (500K+ members) - "Easy Family Dinners." "Meal Prep Sunday." Kitchen tools sell themselves in comments. "What knife is that" and "where did you get that cutting board" on every recipe video. The recommendation comes from a peer not an ad. Trust is pre-built

What all 5 have in common: a recommendation from someone in her facebook group who shares her problem converts at rates no ad platform can match. These groups have tens of millions of members spending billions

The playbook: faceless page. 3 educational posts per day. One product recommendation. Members share into groups. One share into a 400K group = 500-2,000 new followers. The loop runs itself. But "I run faceless health pages for women over 45 on facebook" doesn't get respect on ecom twitter. It gets $20-50K/month deposits though

Here’s a summary of what each team now need in order to qualify at the World Cup:

Group A:

• Mexico top the group regardless of MD3 results

• South Korea need only a draw to finish in the top 2.

• Czech Republic and South Africa both need to win to realistically have any chance of qualification

Group B:

• Canada are essentially guaranteed qualification and simply need to draw their game with Switzerland to finish top

• Switzerland are also effectively through but need to beat Canada to finish first

• Both Bosnia and Qatar will be fighting for the win in their game. A draw is no good to either team

Group C:

• There’s a great chance that Brazil, Morocco and Scotland have all qualified for the knockouts already

• Brazil and Morocco will be looking to win their games by the most goals in an attempt to win the group

• Scotland are likely fine already but a draw would secure qualification

• Haiti are already knocked out

Group D:

• USA are already the confirmed winners of Group D, regardless of their result in MD3 (they have the H2H on both Australia and Paraguay)

• Australia simply need to not lose to guarantee second place

• Paraguay are likely fine regardless of the result but a positive result against Australia is the aim

• Turkey are knocked out already after losing to both teams above them

Group E:

• Germany will be group winners regardless of the result in MD3

• Ivory Coast simply need a draw to secure 2nd spot in the group

• Ecuador need to beat Germany as 2 points doesn’t look like being enough to be a top 3rd place side

• Curacao also need to win their last game to have a chance at qualification

Group F:

• Much like Group C, the top 3 of Netherlands, Japan and Sweden are all likely through regardless

• Netherlands and Japan will both want to win to try and hit top spot

• Sweden will finish top 2 with a win but a draw will also be fine

• Tunisia are knocked out

Group G:

• A point for Egypt will see them win the group unless Belgium win by 3 or more goals

• Both Belgium and Iran will likely be fine with a draw but they’ll be looking to win to make sure

• New Zealand realistically need to beat Belgium to stand a chance

Group H:

• A draw for Spain will basically see them through as group winners

• A draw for both Uruguay and Cape Verde will likely see both go through, with Uruguay finishing 2nd

• A Uruguay win will see them likely win the group unless Cape Verde wins by a greater margin

• Saudi Arabia need to beat Cape Verde to stand a chance of qualifying

Group I:

• Both France and Norway are through regardless

• France only need a draw to win the group, Norway need a win

• Senegal and Iraq will both need to win to stand a chance of qualifying. A draw is no good for either team

Group J:

• Argentina have won the group regardless

• Austria simply need to avoid defeat to finish 2nd

• Algeria likely are through but a positive result is ideal. A win is even better, as it would confirm 2nd place

• Jordan are already knocked out

Group K:

• Colombia are already through but need to avoid defeat to win the group

• Portugal are also effectively through but will be looking for a positive result

• Both DR Congo and Uzbekistan need to win.

• A win for DR Congo will basically guarantee qualification but it may still not be enough for Uzbekistan due to their poor goal difference

Group L:

• England, Ghana and Croatia are all effectively through

• England will look to beat Panama to secure the top spot.

• Ghana need to better England’s result or win by 2 more goals than England

• A draw is fine for Croatia but they’ll be looking to win to finish in the top 2

• Panama are knocked out already

That’s just about everything! If you have read the whole way then I salute you but hopefully this helps!

Your competitor's Shopify sitemap at /sitemap.xml shows every collection, every product, every page, and every blog post they've ever published - their entire store architecture visible in one URL

Type any Shopify store URL + /sitemap.xml. Hit enter

You're looking at:
- every collection they've created (reveals their category strategy and how they organize products)
- every product they've ever published (including ones hidden from navigation but still live)
- every page (about, FAQ, policies - shows how complete their store is)
- every blog post (reveals their content strategy and SEO targets)
- last modified dates on everything (shows you what they updated recently = what they're actively working on)

The sitemap reveals things the storefront hides:
- hidden collections they use for ads but don't show in navigation (these are their highest-converting landing pages)
- products not linked from any collection (test products they're running ads to directly)
- blog posts targeting specific keywords (their SEO strategy laid bare)
- recently modified products (they're actively optimizing these = these are their current winners)

Combine with /products.json (entire catalog with prices and variants) and /collections/all?sort_by=best-selling (actual best sellers by sales volume)

Three URLs. 60 seconds. You now have their complete store architecture, their product catalog with pricing, and their best sellers ranked by real performance

One operator audits 3 competitors every Monday using these three URLs. Takes 10 minutes total. He knows which products they're testing, which ones they're scaling, which collections they're building ads around, and which prices they're charging. His competitors spent 12 months building their strategy. He reads it in 10 minutes every week

Every Shopify store on earth has a public sitemap. It's how Google indexes them. It's also how anyone with a browser can see everything they've built. The store owner is never notified. There's no way to prevent it. The sitemap is required for SEO to work

Your competitors can see yours too. The question is whether you're the one doing the looking or the one being looked at
