Being a carpenter might involve handling tools that are potentially dangerous if handled without one's full attention. So, may I suggest that one avoid such endeavours unless one is able to fully focus on the job at hand.
Ever tried it? You sound someone who has a great deal of experience in the field.
My father was one and I loved the smell of wood in the workshop.
I would have loved to be a carpenter. It's one of those professions that might never go away. Even having mass production stuff, there are still people who prefer the human touch and the originality in the arts and crafts.
There are construction carpenters (framers) that work outside in the sun, rain, cold hammering dimensional lumber together to construct the skeleton of a building. It's physically demanding and chance of injury is significant.
There are finish carpenters who do the detail trim work like window and door frames, baseboard, wainscotting, etc. You work indoors but still on-site.
There are cabinet makers and furniture builders. You probably work in a fixed location/shop.
Probably a bunch of others that I haven't thought of.
