I believe in fixing things starting from the bottom up so here's a link to an indispensable piece of equipment for any PALS who is losing his hand strength or for anyone who wants improved hygiene. The only hand strength required to operate it is the ability to poke a button. Warning: once you have used one, you will find not using a bidet somewhat disgusting. I really like this model for its ease of use, seat and water warming features, automatic drying and deodorizer (this function is much more effective than a bathroom fan) and adjustable features. I have not used others though. It is available on eBay for $600 or for a lot more elsewhere. I recommend getting the elongate version rather than the round model which I find a bit cramped for space, and no, I'm not fat.
