You want to get rid of some habits as quickly as possible. Nail biting is one of them, but there is still a plus.
There are bacteria on your hands. By biting a nail, you always expose your body to a very small number of those bacteria. Maybe not a fresh idea, but it gives your immune system a boost.
Memory
Our immune system has a memory. Every time our body fights bacteria, a note is made, so to speak, so that our body knows how to fight the bacteria next time.
Prehistoric times
It could even be that nail biting is very natural. There used to be no nail scissors, so nail biting was probably one of the ways to shorten your nails.
Beautiful nails
Despite the benefit for your immune system, you may still prefer beautiful nails.
