Retirement Home Keys - Easy does it...

I was at my grandmother's retirement home a while back, and noticed something about her room keys: they had particularly wide "handles," wings that were easily 3 times as wide as normal keys (like the little one in the photo). And I realized that this makes sense: elderly folks have a tougher time with both dexterity and hand strength, so a larger key will help them handle and turn it better. Actually, it was pretty nice for me to use, too! In any case, it's a good example of making a choice with a keen awareness of the needs of the user.
