Impressive and well detailed article on this subject. Washing hands should be embraced by everyone as it saves us from hospital bills and illness. I really appreciated this point below:

it reduces the spread or exchange of germs since one does not touch the soap like a bar soap

I have never thought about it, but that is true. Bar soups can still carry germs due to physical contact. But a liquid soap does not pose that danger. I will continue to use liquid soap for hand wash.
