Why do people wear high heels?

People always are telling us how bad heels are not only for your feet, but also for your hips and back, so why do we still continue wearing them? Not only do we still wear them despite all the warnings but we continue to increase the height of the heel as well!
For an outsider looking in this may seem crazy but trust me, there's method behind the madness.

So back to the question in hand, why do people wear high heels? It's purely cosmetic really! High heels give the illusion of longer, slimmer legs and they also give an extra few inches!
If that doesn't explain enough for you, and you're still wondering why women endure such pain and risks to their bodies just to make themselves look a tad bit better, well the answer is simple. Women are incredibly vein creatures. There's no other way to put it. It's obvious they are though. They wear make up, use sun beds, even pull tiny hairs off of their eyebrows just in the hope that they'll look better!
The real question is though, is it realy worth it? I'll leave you to answer that one for yourself.
