Hi Dave,
Had mine hernia's done at 44 (left) & 50 (right). I know the later one took twice as long to recover (about 6 weeks) than the first one. Be mindful of the internal stiches as well & don't raise your hands above your head for a while.
Oh, and if you get the urge to sneeze post op, push down on bit between your nose & top lift. A lovely nurse told me that (after I had sneezed

).
