I know some of the rest of you old farts are getting on up there in years, or have health issues too. Just a word, when you go to install grab bars, do it yourself if you are able. Also they do not have to look like crap anymore so you can make the missus happy too. I just replaced the towel bar in our hall bath with this. They are available in different colors too.
