As someone who started programming professionally at 25, and stopped professionally at 60, here is my experience: At 25, I could do a decent job of "drinking from the firehose". I could learn new things very quickly, and retain what I learned. At 60, the time it took to understand stuff grew longer, and the ability to retain it basically disappeared. I was programming in Ruby on Rails, and learning about a new gem or a new test environment was 'fine', but the next day, I needed to return to the documentation at length to refresh myself. It made being productive super difficult. I still do very small hobby projects, mostly using stuff I learned 10 or 15 years ago. This might not be true for everyone, but guaranteeing that 'anyone' can program at any age is just not true. Especially not in an environment where you need (a) a language, possibly 2 or 3 (b) a framework, (c) a test framework (d) an IDE, (e) a production environment (f) a source control system (g) a problem tracking system. YMMV. You need to check it out for yourself if you're considering it.
