Downsides of Poker

[PoppinFresh]

Inspired by ggbman's thread about teaching his sister to play poker.

I've been thinking a lot about the effects that poker has had on me, but I'm finding it difficult to really pinpoint what has lead to what in my life or come to any conclusions.

Just looking for general thoughts on what the negative effects of poker are and why they occur, and why poker seems to effect people differently than other games/sports besides the obvious money factor(obviously money is a huge part of it, but an elaboration on why this is true would be nice). Thanks in advance
