That advice comes from Scott and Helen Nearing, while living the good life. Just though I would contribute to a previous thread. I do not oil my shovel handles, btw, Scott did though, and lived into his 90's. I wonder how old his shovels were. I have lost more shovel than I care to recall. I used to do a lot of mechanic work, snacking along the way with dirty hands, so I probably have had an oil sandwich. Brake dust was the worst, not to mention gasoline running down my arms while changing a fuel line or tank. I am glad it is not still my primary line of work. Welding is another place where it is possible to breath in some nasty stuff.
How about nine lives? I wonder how many I have used?
