Re: Don't try this at home...
There's a balance of risks involved in all these things, and as more becomes known, that balance changes.
I recently read that electric shock is now believed to be a predisposing factor for motor neuron disease, so it's no longer a simple case of 'I got away with that' - the effects may be seen many years later. The same principle has proved to be true for a number of substances and activities discussed here, and no doubt there are many more waiting to be discovered.
