Like I said to my friends years ago when I started using reading glasses:

"You know you are getting old when you have to go to the store to get some 1.5's and they are reading glasses."

(Those of you that never had the experience of "rolling your own" probably won't "get it".)

Having a few extra pairs never hurts. I have duplicates of things at work that I couldn't function without.

Look at Zeke. He has extra pairs all over his shop, probably has a few extra razor knives, and even has a spare user name if he needs it.

That's gold Jerry gold ! :D
