93 years & 231 days old Ann Esselstyn dead hangs for 2 min 52 seconds! To set new WR. (Maybe we call it live hangs instead now?) Distal strength reflects many things.
Your body produces cells with mutations every day, and some could potentially turn cancerous. Your immune system, including NK cells, helps find and destroy many of them.
Sleep is essential for a well-functioning immune system.
One night of poor sleep drops NK cell activity by 70%.
Go to bed on time tonight.
