Please help with school paper!

[Chaddycakes]

My paper has to be about a idea/invention that can make the lifestyles of individuals healthier or easier. It has to be health related. Also it has to be an idea that can be sold to a company for a profit. Im having troubles thinking of anything good. I had one idea of a coat that had a built in heater that you can adjust lol i know stupid... Any ideas are welcome that match the criteria. Also use your imigination because money is worthless to these companies as long as the idea works... Any help is greatly appreciated.
P.S. i also have to give a presentation about this product so try not to make it too ridiculous.

And, uh, why would someone give the idea to you rather than selling it him/herself?
