Well, I'm alive. I think.
I've lived for over a decade with asthma, so I'm used to the out of breath thing, though jsut HOW out of shape I am caught me by surprise (lasted all of 20 minutes before needing to collapse on the grass for a while).
But what really got me was that I apparantly can't run full speed anymore
Oh, I've still got the mechanical ability to, I got up to full speed. But my sad, old, fluid-filled lungs just can't keep up with the oxygen demand. Sprinting down the field, I could suddenly feel my legs go into oxygen deprevation mode. Fortunately, I still know how to take a tumble at speed, so no harm done. But that was a little depressing.
