Just for the unwary I saw some statistics about causes of death a while ago. Amongst them was the fact that, on average,

 THREE PEOPLE A YEAR DIE FROM TESTING 9 VOLT BATTERIES ON THEIR TONGUES IN THE UK.

I recently joined St John Ambulance as a volunteer and I would much rather not have to use my CPR skills on a fellow Time Nut. 

Please always think safety first.
