Haha, ironically I wasn't that interested in cadaver lab anatomy - the smell didn't help. Sort of a surprise I would up in surgery. Real deal is a lot more engaging. Smell can be plus or minus context dependent
Yeah I think its also worth considering that carrying strongside OWB/IWB isn't great for one's back either. Probably especially if you also have a long career of carrying lots of other weight on your belt.
Either way I think it's not likely that carrying a firearm is going to be the most terrible, self-harmful behavior we engage in regularly. More likely that will be what we shovel into our mouths every day and the amount of time we spend seated.
