What will you do when you retire?

I'd like to start to learn drumming again when I retire. I'll make my own music studio equipped with soundproof facilities. Also, I'll buy the highest quality drum set for myself. I want to take drum lessons to practice everything step by step. Beyond this, I'll participate in any kind of band to play and share music with others. If I have enough time, I'd like to learn how to play the bass too. This is a melodic instrument unlike drums, so I can broaden my musical insight. Actually, I'm trying to make music my hobby again because I think that work and life balance is also important. I guess I can continue my career without being exhausted doing so.
