My father had his removed about a decade or so ago.
He was back at work running a bulldozer in less than 15 hours from being released. He claimed he hadn't felt as good as he did the day after the surgery for several years.
We never get anything done, he shits all the time. I'm a little pissed to hear its a legitimate side effect because I cuss him every time he leaves me hanging on a job to go take a dump.
