The Human Chicken-leg effect

First week back to school! and literacy still going. This weeks reading activity was
about the "Chicken-leg Effect". After reading this article, I learnt that when there
is no gravity on earth, lifting something heavy won't make us stronger. Because it
is floating. I also learnt many other things but the fact that I was mostly interested in
was that when we are asleep and our body is flat, 80% of our blood from our legs go
up to our upper body and mostly end up in our chest. Go through this presentation to find out
more about this activity.
