The Weather Replay app allows you to see what the weather was like anywhere in the world since the 1940s. I was born in southern Germany in May 1983 when the sky was clear and night temperature hovered around 5 degree. Surprisingly addictive tool. Great for historians and biographers too!

@authoradraeanna It's almost impossible to find weather information in occupied Europe in the war, so I'm geeking out.

In 1943 the US introduced the “Basic Seven” food groups, an early ancestor of today’s food pyramid. Three of the seven groups were fruit and vegetables. Milk had its own group. Meat shared a group with beans and nuts. Butter was an entire food group. The focus wasn’t weight loss. It was keeping wartime America healthy, strong and productive. Source:
