“I wanted to invent an engine that could run for ever. I could have developed a new train, had I stayed in the railway. It would have looked like the AK-47 though.”
“But when you lose a family member or something tragic happens, that stays with you forever. You never get over it. Knowing that you have to deal with that for the rest of your life... Football is important, but not as important as you once thought it was.”
