mechanic - lol. know why mechanics drive ****ty cars? they get home and dont want to continue doing their job.
HVAC - meh, the job is a lot of work. you'll also have to do a lot of work outside as bill said.
electrician - if youre into electrical, skip the manual labor and go straight for the design position. cushy job with a large pay grade. ask me how i know.
CNC - this is a good job NOW, but it's a super dying trade in america. it's just too cheap to make some dude in asia do it. seriously, im not joking. this field is dying for a reason.
i am currently an electrical design engineer for a company that makes loading dock equipment. my job is to put together special requests for customers that isnt offered on our normal price list. give that, the circuits i work with are actually very simple. however, electrical tends to confuse people and because i understand what i am doing i make some decent bank for it. i sit at a desk all day and i screw around 30% of the time i am here. granted, i got lucky and fell into a great company with a fantastic line up of co-workers, but that is something you have to strive for in the end.
all in all, don't cheap out now. put in your time in school and use that expensive piece of paper they give you to get ahead of others in the job market. it is really the only thing that is going to save you from the hard labor jobs mentioned above.
also, if youre interested, union labor can be rewarding if applied correctly. i just hate unions because they drag the people down that actually know what they are doing. therefore, ill never be pro-union because at the end of the day im better than you so i deserve better pay and benefits.
