Why Do We Do This To Our Selves

We have all done things that we like but have adverse effects. Why do we cause our faces to be contorted like this just for a few seconds of enjoyment.

For example we have this candy in our office. I really like it but it makes me make this face. SweetTart chewy sours. They are so sour and awful but I love to eat them. Why is that? Like eating hot stuff! It burns the crap out of mouths but it taste good so we eat it!

It doesn't have to be with just eating things, it can be with any activity, like riding roller coasters. Those things can scare the life out of you but you ride them anyway!

Michael Todd always makes fun of me. He always asks me why, why do you keep doing that! LOL

Why do we do these things?
