OMG, when I first read this I thought you meant £75 British pounds. I was like "hell, I could lose that is a day".
Haha, since this thread is in gambling section I thought about the same, like wtf? A normal guy can lose this in seconds.
75 pound is 34.0194 kg, so it's not impossible to lose that weight if you are over 120 kg. What would be the odds? I don't think anybody look this long term bets positive.
I'm not sure what someone else would be comfortable with... I do gamble so I wouldn't mind a healthy wager.
