What humans need is tougher skin.
Sure we've all heard that expression 'thick-skinned as in:
The definition of thick skinned is someone who is not easily upset or insulted and who can take criticism well. An example of thick skinned is a person who is insulted and simply says "whatever, I don't care."But I'm talking of literal thick-skin not metaphorical thick-skin.
I propose coming up with a skin cream that does the opposite of all of those hellishly expensive skin softening creams that women use.
Have you ever had a callus on your toe or thumb? Musicians get these a lot especially the silly buggers who play stringed instruments. I guess if they played their instruments with their feet as well as their hands they wouldn't have a problem with cut toes.
My idea is to invent* and market a cream that roughens up the skin on hands, feet, knees, elbows, top-of-the-head for old bald bastards, shins and any other parts that are prone to getting cut or grazed when outdoors gardening of playing sport.
I think I'm on a winner here and am accepting start-up funding from interested investors. Are you in?
* I'm the ideas guy. I'll have to contract out the cream creation to some scientific guys.
