This is something that came up in a recent conversation I had with some friends about jeans. It's silly, but somehow it has me worried. They mentioned that keeping your wallet in one pocket for extended periods of time (over years) can actually affect the alignment of the spinal column and ruin your posture later in life. It's this true/possible?! Has anyone ever even heard of such a thing? Despite what you guys may think from my posts/typing or whatever, I am a horribly naive guy and I just tend to eat this sort of stuff up. Is it true?
