I think that depends on where we live, but I can tell you that I always go to different stores to pick up equipment and different things and I rarely see people my age or younger.I remember about 8 years ago a husband of a nurse that worked with my wife put in a new air conditioner and furnace for us. His company did commercial, hotels , restaurants etc. He was in his mid forties. I asked him about younger workers getting in the trades and he said he was the youngest one at his company.
