That's a good story.
It reminds me of last Summer, before I had to quit working out due to a health issue. I was arguing with someone at the office about strength. He said it was pointless to be strong in life and that's why he stopped lifting (total lie, but that's a different topic). One of my points was that being strong could help you in an emergency in real life.
That same day I left the office bit later than usual, took the tramm and this drunkard tried to get out on the next step, but was too slow and the doors closed, but the security system reopened them, but the tramm driver didn't realize, so the tramm started going faster and faster. The drunkard was like, half hanging from the door and too drunk to step back.
I quickly crossed the wagon, grabbed him and pulled him in (mind there are two big steps by the exits at the tramms). I suppose that an untrained person would have been able to pull him in as well, but that day I really felt I had to train harder to get stronger.
I started lifting because a friend pressured me to do it. He was sure that it would help me with my confidence, depression issues, etc. It really did.
Now I want to be very big and strong. I know it will take a while, but I enjoy the time spent at the gym, so it's all good.
