I've been retired for 18 years and still out there with my cars. I work a little slower now at age 75 but it is still fun to do. My mistake was not turning my pole barn into year round work area, Heat and cooling plus insulation and better lighting. Also ran out of work space with a 40 x 40 pole barn so I am now adding another garage with all the comfort features to work in year round. Something I should have done before I retired.
