Lately, I translated an article on the optimal moments of the day to go skating, according to your body rhythms.
Obviously, it works for skating as well as for any physical activity: the article breaks down the different times of your body's circadian cycles (internal clock) as well as its chemical reactions to those different phases... and concludes with the best time slots to be active according to your body's awakeness.
The specific vocabulary is obviously explained with everyday words, and the article highlights the main ideas of the concept.
I am not writing a post to advertize for it, though:
As soon as the first lines, it re-activated forgotten memories carefully filed in a corner of my brain.
