Heck, I went back to University at 50, for my Third Degree. Phew! That was a pain but worth it too. I think we have all heard the talk/warnings/speculation that we will change careers, companies, titles, homes a Myriad times over the course of our life. It is more common now. People don't just die off at the age of 64, as they did in the 1900's. Some of us may live to 80 or 90 and maybe beyond.
I bet since you are noticing this trend in others, means it could well happen to us all. Having been a biochemist, a sales person, a high school and college teacher I realize that I could never eat ONLY meat and potatoes all me life.
We are all in this together ;))
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
