Haha... well, it's really hard to be "serious" in this topic, but I'll try.
The one thing people didn't really mention is toes/feet (actually one person mentioned toes). Personally I have waxed my toes and the top of my feet a few times and then let it slowly grow back before doing it again, you don't want to look like a Hobbit afterall 😛
Besides that, personally I shave my face, occasionally trim under my arms, rarely trim my legs. Thankfully I'm not a super hairy guy...
And FYI, continued waxing over time does reduce growback, which is why if you have a hairy back or whatnot, it would be better to wax than shave as it will reduce the amount of hair that comes back over time. And no, I don't know this from personal experience, lol. I simply know it because my mother has waxed her legs for many many years and very little hair grows back on them anymore.
