Although it is true that this rumour has been circulating, and even become a
popular 'truth', it is also true that there is absolutely no evidence to back it
up.

I have challenged anyone repeating it to give me *any* evidence to substantiate
it and I have never heard a shred of evidence to prove it.

It is just one of those things that goes to show how much of what we 'know' is
not true.
