just a number?

Tomorrow, I'm turning 38. Just by working on getting healthier, I feel better than I did when I turned 28. I'm already a lot healthier than I was at the beginning of the year. I've been eating less and healthier, I've been burning 2-3x the calories I've been consuming. I haven't been losing much weight wise, but doc says I'm gaining muscle. My clothes fit better, my skinny jeans are now my fat jeans (need to shop for a new pair). I was discouraged when I saw the scale, but then I noticed the other differences. I am excited about those differences.
