I've worked with the elderly for a long time through volunteer at a nursing home and as a private caretaker. Here is my list of things I'm not yet fully comfortable with. Cleaning up after somebody throws up, helping with wiping, bathing the elderly, clipping toenails, anything with needles, some nursing home policies that I don't like because these are people and we aren't supposed to be speeding up their dying process, weird smells. Well just to name a few. Anywho, if you really love the work like I do and you love to sit around listening to old stories, you'll get over the cringy things.
