I now have two high receptionists chairs, I used to have four, but I found I can scoot about between machines without having to stand up, so a couple were given away to friends.
There are lots of ways for us to carry on in our shops, I myself have power feeds on everything except the topslide on my lathe, but because that is only for short work I can still cope with it.
I have digital hearing aids and have found that a good technician can set them up to eliminate almost all the Tinnitus problems to give me nice full range hearing while I am wearing them. My problems start when I take them out and try listening to the TV in the evening, I have to turn the sound right up to be able to pick things up fully. Luckily, my neighbours can't hear my TV when going full blast, but my little dog buries himself under a pillow so that he can sleep.
If you don't try it, you will never know if you can do it!!
