same for me. One of the main concerns I have with "Could I be doing this at age 50" is the health aspects. I've noticed my eyes declining, wrist pain or other repetition-caused pain, hip pain, at age 30 after doing this job for 8 years. I do use a standing desk and alternate throughout the day. I'm probably significantly more active than most programmers (walk 20k steps a day, do cardio or weightlifting daily). I have concerns about how I will be able to do this job longterm.
