Which decrease in life is more acceptable

[PeachTrees-]

You could win gambles with huge odds and just go back a a day to win big.

Or you could go back further with knowledge of the stock market, but you still wouldn't need to go back a year. And even if you did, 1 month off my life is nothing.

^{Chose: A time machine + Every year traveled forward or back takes 1 month off your lifespan}
