How old was you when you started in this trade? I am just curious, because i am 38, and just started 5 months ago as a install helper, and go to school at night. This is a second career for me. Most guys at work are much younger then me, and tell me i am crazy for wanting to do this stuff. LOL. In my opinion you are only as old as you feel, and i can crawl in those attics, and crawl spaces with the best of them. I eventually want to become a Service Tech, so i go to school, and put one tech tool a month on the employer tool account to show the employer my future interests. By the ripe age of 42 i will be done my 4yr school, and hopefully be a service tech. Green service tech, but a tech none the less.
