A list and detailed descriptions of 10 UNSOLVED everyday problems

I'm looking for some creative input from people of all walks of life. The mission is to come up with 10 UNSOLVED everyday problems that are in need of solutions.

To qualify for this job you must submit at least ONE such problem, so that I can make sure you got the idea. Your proposal will only be accepted if I, after doing a bit of Googling, will not be able to find an existing solution to your problem.

The job is only complete if I'm unable to find any existing solutions for all 10 of your problems.

Please note that the following problems/questions will not be accepted:

Any BIG scientific questions and problems will not be accepted e.g.:

or

GOOD LUCK!
