I'm 73, and have been retired since 2015. I work to keep from becoming bored or "losing my edge".
I even taught Embedded Computing in high school for three years. I stopped that because I don't want to spend the money or time to get a certificate. The teaching was a blast. The school was unbelievably supportive of me.
You are so lucky to be doing something you love. I envy you.
I did all the stuff you claimed, but not taught.
I could not stand dealing with the liberals that administer those that “teach” these days.
They even offered to pay for my accreditation.
I make more money sitting on my a$$ in one day drinking beer than any 4 days teaching young “special” Hawaiians how to program an FPGA to emulate an old 68340 or 8051.
I fully understand why kids don’t want to work.
This political Woke stuff is BS.
