This video is a few years old, but definitely worth watching, even if you've seen it before.  This Englishman, Ashley Revell, sold everything he owned.  He ended up with $136,000.  He then traveled to Las Vegas, where he bet his ENTIRE LIFE SAVINGS on one spin of the roulette wheel.

Now I'm not a gambler at all, other than a few bucks in a slot machine here and there, so I can't even begin to relate to this.  But it actually made me a bit nauseous watching this video.  Would you ever do something like this?  What's the most amount of money you've ever bet?
