my fingers smell unusual?

Wash your hands, several times a day. Hands are dirty and they sweat and stink. If you have a poor diet the smell can get into your body and seep out through your pores and make your sweat smell worse. You really should be washing your hands about 8 to 10 times a day depending on what you do and what you touch. Washing your hands is the number 1 protection against colds and flu.

The proper way to wash your hands is to rinse them under water use a small amount of soap, more soap is not always better, lather your hands rub them together scrub your palms against each other, interlace your fingers and wash over your finger tips and finger nails. You need to scrub your hands together for 30 to 60 seconds, sing the ABC song while you wash your hands or sing Happy Birthday To Me two times then rinse your hands thoroughly under warm water and dry with a clean towel. If you wash your hands properly you do not need antibacterial lotion. Do not substitute antibacterial lotion for washing. Antibacterial lotion or gel is a sterilizer not a cleaner, if you clean your hands properly you don't need to sterilize them.
