I got my second degree when I was 57 and then went straight on to grad school. I did not have the grades in 1972 when I got my first degree and things were much different back then, both grades and health mattered, they could ask you on your application form if you'd ever had treatment for a mental illness, etc. and lying was not an option for me. My second degree and grad school were completely online, which I preferred. I dropped out of grad school though, it was not the subject I really wanted and I had health problems, etc. so I took the money and started a different project.

I would see how you feel when you feel you are ready and interested? Things keep changing with the technology and subjects to be studied, where and how, etc. In 5-10 years it could be a whole different world we can't imagine now?
