Strip a man naked and ask him what he has got in his pockets. Most people will agree about the answer: nothing. He doesn´t have any pockets. Now, imagine having a million men stripped naked. Claim that all of them carry something in their pockets (which they don´t have) because one of them once used to know a guy who carried something in his pockets. That´s the sort of thing homeopathy claims.
That ain't right!
