You get to know the principles behind the code pretty well after 2 decades at it. In Los Angeles we just don't seem to have the same level of overt ageism.

Maybe other people your age couldn't learn this but your mind is much sharper than average and stays sharp thanks to daily mental workouts of solving hard engineering problems.
