ambidextrous     Ambidextrous means that you are able to use both hands efficiently. It means that you can write with both hands. That's at least part of it.
Surprisingly, perhaps, itâs almost impossible to smell your own bad breath. Youâve probably tried cupping your hand in front of your face, exhaling through your mouth and then sniffing for the odor that others find so offensive.
Your smell receptors in your olfactory bulb, which resides in your nasal canal, are very sensitive. But you wouldnât want to smell every smell all the time; you just want to smell new smells. So your smell receptors turn themselves off when an odor persists. That can be bad news when it comes to your breath.
