What singular invention do you think will last forever or at least the next few hundred or thousand years?
"By Singular Meaning a single invention as opposed to say the internet, or the computer, which is less of a singular idea"
Personally I am going with the toothbrush, honestly it's one of the most awesome inventions ever created, helps keep your mouth clean and fresh breath. I love my toothbrush personally, and it's one of those things, I really need to have with me, If I was on that Naked and Afraid or something, it is for sure one item I'd like to have.
