I'm 43 this year. I started out with matlab, then C, then R, then Python. I'm still coding and doing a decently paid job with good work/life balance.

If you have interests in doing something, it's never too late. And tech job is particularly well suited for people not good at talk talk, and is in high demand as long as you can prove your skill, which is actually simple - tech interview is the most difficult to fake.
