Re: Nose hairs have disappeared!
You have some really interesting thoughts there comsat2!
I think nose hair serve two purposes:
1) they filter out the impurities and 'hold back' the bacteria and viruses from outside (I remember someone told me to breathe through my nose in public places when the flu is around - so that the virus in the air is filtered through the hair in the nose),
2) as comsat2 said, nose hair might help to soften the sting of the cold air during winter. It is quite possible. Everybody who experiences really cold winters knows how badly the inside of the nose stings...
However, I don't think that nose hair is so important to that extent that one couldn't live without it. Don't think there is a real reason to worry! Your body will decide itself whether the hair will grow back or not. The body knows what's best for it.
The main thing is - the parasites are gone! Keep them gone forever and it will be allright!
