I think I am going to die.
I've never done any exercise.
Sometimes when I'm a bunch of hours at the PC and suddenly I get up (like going to the bathroom) I feel like dizzy, my head feels like exploding, there's a few seconds blackout and It all last a few seconds.
Today I helped moved a furniture, I was sweaty, feel like shit, feel dizzy and overall It was unpleasant.
Am I going to die?
