Today i am appreciating the physical effects of activity on my body. Following last night's race, i can barely walk, only drag my feet along the ground pathetically. It feels like someone has kicked me in the back. How can my back hurt after running? I do not have the concentration to read or to focus for any decent amount of time.

I find it really interesting to observe how one's body responds when put under unusual physical strain, how it can impair and have a consequential effect.
