Finger food is meant to be just that, not meant to be eaten with utensils which would include finger cots. One of the biggest reasons why people are always getting sick in today's time is they keep their hands too sterile I can look at a guys hands and pretty much tell how many visits to the Dr he does each year by how sterile clean they look after he has been working on something. I've seen technicians, you can't call them mechanics any more because they go through a dozen pairs surgical gloves every-time they do anything under the hood of a vehicle. most regularly visit the pharmacy or a DR for any little thing.
There is a discussion going on on another web site about people getting sick from eating what ever.
My comment was that most of the people alive today would wind up in the ER or under observation of the CDC if they were to eat the things that was considered good food bought from a store 100 years ago. At one time humans could eat things that would make a vulture ill without ever worrying about getting sick them selves. But in our so called advancement we had lost most if not all of our tolerance to things like that. In my opinion a lot of it is because we try to stay too clean.
I had an uncle who had lived up in the remote mountains all of his life, at the age of 80 he had never been to a DR. One of his brother's children finally talked him into coming to live with them for a while since he was in their view getting too old to take care of himself. A short time later he became ill from some stomach infection pretty soon he was making weekly visits to the DR. After about 2 years of this he decided he had had enough and if he was going to die it was going to be in his own home up in the mountains, He did pass away eventually 10 years later from wounds encountered fighting some animal over a fresh kill he had made but the wounds took nearly 6 months to get the better of him.
