What if..

Saw this movie "Paycheque" this weekend. Have always wondered when I am watching these action packed movies - what if I had to run from evil people like that? Do I have the stamina to run across the city or would I get caught, be tortured and killed simply because I dont exercise enough to have the stamina to run from them? I always come out of such movies resolving to exercise regularly. Usually, I then head for a burger place to get myself some food and prompty forget all resolutions of exercise.
