Insomnia and Sunburns

So I've had some bouts of insomnia lately and have consequently gotten into a bad habit of going to bed late, so once again, here I am wide awake and needing something to occupy myself with until I can fall asleep, so you can all reap the benefits of my crazy late night idea. I was doing a short outdoor activity today and decided not to put on any sunscreen in order to get a little color, I really didn't think I'd get burned quite like I did, but obviously you can see the results below, so my question to you is, how long was I in the sun to result in such a burn? I kept track of how many minutes I was out there, so I've decided to take a little poll, and who knows, maybe there'll even be a prize for the winner. So place your vote as a comment to this post and after a couple of days, I'll let you know who was closest. P.S. It's kind of awkward to take a picture of yourself like this, so don't pay much heed to the strange unflattering poses, but they do show off the sunburn pretty well.
