"And I don't relish the idea of having my molecular bonds ripped apart by my kitchen countertop."
Each time a disinfectant like 3% hydrogen peroxide is locally applied to you, the top layers (few cells depth) of you at the point of application are chemically disrupted. But like a good onion, you have a lot of layers and could spare a few, especially for a good cause. Besides, as long as you are alive, they'll grow back, and soon you will have anothe annual ring.
The bacteria, on another hand, are single cells - only one cell deep. So when it goes, so do they.
Willie, are you a good onion?
