There's huge differences in the individual trades and what it means for your body. The vast majority of my friends are in the trades (I'm the outlier with an office job) and over the course of 20 years, many things have improved. Better tools, machines to do the very hard parts, etc. Some trades aren't super physically taxing, whilst other are, like plasterers. So the comparison is complicated, and you'll also have to take into account the physical and mental wear of an office job.
