If you find that you need to let go of the problems of the day, let me suggest that you go to the website of http://www.freerice.com. You can help feed the hungry of the world. It is great fun..
Then if you need to sharpen your wits...go to http://www.sporcle.com and play a few mind games.
I need to do this everyday just to let off some pressure. Real estate is hard right now.
