It's not a problem.
I went back to university, and I obtained a road construction and heavy vehicle driver's certificate.
I also obtained my Class 1 licence, since I had worked with heavy machinery throughout my career. I discussed it with my wife and we determined that it was probably a good choice. It wasn't. I tried to work in civil society, but it didn't work out. My social reintegration was a total failure. Eventually it was recognized that I had a diminished earning capacity, or DEC, I think—the names change every month. I'm staying at home now. It was an appropriate choice.
