To put age into perspective: Grace Hopper first entered computing at age 38, completed the first compiler at age 46, influenced the design of COBOL at age 53, wrote COBOL for the Navy through her 70s, retired from the Navy aged 80 and *then* became a consultant for DEC(!) 😍

You were forced to either do unpaid labour or join the military when you were 18? Sorry to hear that. Forcing people to do things is not the same as doing it with their consent.
