Used to be that a person would be declared “dead” when a lack of a pulse showed their heart had stopped beating. Thanks to modern understanding and things like CPR, that’s no longer necessarily the case. Now, scientists at Yale are working on doing the same thing for the brain.
The adaptability of human physiology to even the most subtle of environmental factors will never cease to amaze me.
Since swimmers exercise in a horizontal position, he says, their hearts do not have to fight gravity to get blood back to the heart, unlike in upright runners. Posture does some of the work for swimmers, and so their hearts reshape themselves only as much as needed for the demands of their sport.
This is a bit of an unintentional follow-up on an item from last week. While reading about the myriad of child social media “kidfluencers,” I kept coming across the acronymn “ASMR” in reference to a certain type of videos. It’s not that making ASMR videos is exclusively the domain of kid YouTubers — far from it.
