You know for one thing every body has a smell but it is how one prevents it...it's not whether you are rich or poor, or you can afford good perfumes but in reality it is just a matter of good practice of personal hygiene.. So as not to insult somebody who smells, give him or her a gift of good deodorant, complete kit on personal hygiene(including the book on personal hygiene), if she or he is intelligent enough, he or she will get the message.
