don't let 20 years stop you.
Your skills will be rusty but will come back. Your reaction times will be slower but your common sense probably will have strengthened enough to compensate given 20 years.
Don't know what part of the world you are in but see if anyone there do refresher courses to get your confidence and skills back in order and to see how it feels to be back in the saddle. Then go for it!
