[...lets split up... (OP)]

I accidentally bite my tongue quite often, and sometimes really badly. My aunt told me quite cryptically before she left for London that there was a reason that people bite there tongues and i should try to find out. I've googled it but i can't seem to find anything.

Is there any interesting link between biting your tongue and lets say... eating canned beef, or plucking weeds, or doing body art with lead based paint?

Theoretically all of the above could be sources of neurotoxins which could affect coordination ...

eating canned [food], or plucking weeds, or doing body art with lead based paint?

Applying lead to ones body seems most unwise ...

Exposure to lead and lead chemicals can occur through inhalation, ingestion and dermal contact.

Auntie may be referring to this old wives tale.
