How come in Japan its bad manners to blow your nose in public but its ok to pick it?

Question:

Answer:

I don't know that it is ok to pick your nose in public. However, blowing your nose is something that will tend to attract attention. Nosepicking, on the other hand, can be done on the sly, often using the thumb. It's interesting to watch these people and observe the time delays incorporated before disposing of the bugger and the manner in which said bugger is disposed of.
