Quick post-gym hair...

We all know that we're supposed to get 30 minutes of exercise a day for our health.  According to the month's Health magazine, a recent study found that people who were most fit in midlife fended off heart disease, cancer, diabetes and Alzheimer's longer (I read that stat to my husband and laughed: they did a study on that? I thought it was common knowledge?)  I was blessed with good genetics in that I have never had a problem with my weight (fast metabolism), but I know as every day passes I get older and things are slowing down and becoming less tone. I think it's easier to maintain than to have to build.
