I won $142,000~ in a poker game and I still play, I mean it's big money but it's not retiring money, If I won big and I mean $10,000,000 + I would donate half to charity keep the other, anything under $10,000,000 I would still donate some not half though. Anything under $5 I would just keep and try and help out people where I can.
Guess this is more of a personality question though.
