I disagree about the 35 years old statement. I took a full time in-person Masters in Data Science while also working full time from 36 to 38. I finished it with a GPA of 3.9/4 and I feel it was the best time to do it. It was my third time going to school. The first one was to take a undergrad+grad in CS when I was 18. I did not even know why I was there. The second one was I was 29 for grad school in quantitative finance, why? Because everybody in my professional environment was doing it. I definitely did not enjoy that either and did not learn much. My third time, well I clearly knew I wanted to learn becase I truly enjoyed the matter, no professional need but I simply liked it. And I knew about the math part. Now I am almost 40 and I know almost for sure I am in the same shape or even better to go to school again and enjoy it. To me is just to do something because you like it, not because of social pressure, professional reasons or hype. Also, I think to have a good time while doing it you have to be aware of your personal situation. Mine was totally favorable.
