RE: Low Stamina
yeah, but stamina is how long you can go without your fatigue kicking in.
Look at Rocky I for example...when he first goes for his jog and he runs up those stairs and he's almost crying because he's so fatigued.
Then later on in the movie he runs up the steps and dances around a bit because he can do it so easily...
When he started his stamina was low, towards the end of the film it was high.
I know it's fictional but the fact remains.
