First of all, if this is in the wrong section, please move it. I thought it fits here. But you never know.
Ok, so time and time again, I keep getting amazed by human body and the way it works. What I mean by that, usually is how everything is interconnected.
Recently I decided to finally go and get a massage in one of those asian massage places. Long story short: when the chick pressed at a certain point on my leg-it was back of my leg just above the knee (semi-membranosus probably?), almost my whole thigh and especially the vastus lateralis muscle tensed up incredibly, and then consequently relaxed completely, and all of the sudden i felt how my blood started rushing to that area.
Then she also massaged my feet, and when she pressed and rolled somewhere around the inner side of my foot, my ass clenched up so much that you would be able to stick a sharpened hair in it.
All I'm trying to say here that I'm amazed with the human body and what is it capable of.
This was just one example from one time.
What amazed you about the human body?
