WH,

I know the feeling but got you by a few years. 5'10" as well, 142 lbs., and 36 years old. Wait a while and you will be more and more happy with your build. Over the last ten years I have seen the guys in my age group "putting on the pounds" and they are paying for it. I'm now flying by guys on the basketball court, the same of which used to eat me for breakfast! If you have a physical job, all the better. Trust me, it's not a curse. About the form- I'm no form genius but I do know Michael Jordan had a very flat jump shot, Arnold Palmer has a terrible swing, and Michael Johnson ran way too upright. They all have more money and gold medals than I will ever see!
