Of course the main practical use for diapers is to well, pee and poop in them. But what I refer to specifically is the use of diapers in our actual lives.
I've found that quite a few people online use diapers to movies, games, concerts and places where getting up to use the bathroom isn't very convenient. I've been wearing them to movies since my senior year of high school. (The very first movie I wore them too was Inspector Gadget with Matthew Broderick if anyone's interested. Wet and messed. Theater was empty except for two girls in the opposite side of me and no one noticed.)
But in my current job I've actually begun wearing them to work. I've been using the Attends recently, which I find to be far more absorbant than Depends. I only wish Attends were more readily available than Depends, but I digress. I pee in short bursts all day and the Attends keeps it all contained.
During the holiday season when I was stuck in electronics with long periods between breaks, these were a life saver. Because of the risk of theft in my department and because the store was often packed I couldn't leave unless I had someone cover me, and anyone who has worked in a retail establishment knows how hard it can be to get a simple favor from your coworkers.
I only peed in them. Messing would have been to difficult to maintain in the workplace and at anyrate the smell would have undoubtedly gotten a few complaints from customers that I had no intention of explaining to the boss. (or bosses, as the case usually is)
Does anyone else use diapers for workplace purposes?
