41, can and have been driving manuals exclusively for the last decade. I only learned about 15 years ago when I picked up a beater Datsun 720, but once I went manual I was hooked. Every car I've bought since has been a manual. Keeps me awake and engaged while driving.
I’m the same age as you. Agree with manual keeping you engaged. Another perk is you can leave your keys in the car if you want because no one knows how to drive stick
