One of the best hires I ever had was someone that was 50+ about 10+ years ago. He didn't have a technical background but wanted to be a programmer. It was a big risk but in two years time he became my top developer out performing those with 10+ years more experience. Now I primarily look to hire those with a few white hairs as they are much more stable and cause a lot less personal issues than those right out of school. If I was hiring and you really wanted to be a programmer I would certainly give you a shot at it. If you want to be in technology I don't see anything stopping you.
