Trucking at 59

I am a 59 year old male. I 'm married. I want to continue my current full- time profession until at least age 62 and maybe 65. I am not mechanical and have no familiarity or experience with trucking.

I have thought about going to trucking school on weekends, getting my CDL, and trying to find a job driving a truck on the weekends. Is that crazy?

By the way, I live in the coalfields of southwestern Virginia.
