Being an old guy I make frequent use of my coffee can. My wife is another story. We fish woods lakes that don't have facilities, that however doesn't mean there are no people. In the bass boat it isn't so bad, but we use a 12 foot Jon boat for the woods lakes. More then once she had to dive in the brush (with the ticks and skeets), especially if there was someone else using the lake while we were there.
If I have to be honest, my wife is the size of an old fashion Grandma. The grand kids have just so much time before passing out when she hugs them. I only bring this up so you know a pop can ain't gonna do it.
Please know I am serious about this. It just can't be good to tie yourself up all day, especially when your over 65.
