Oh, but what a journey it were, Pip!

"Nothing shortens a journey so pleasantly as an account of misfortunes at which the hearer is permitted to laugh."

-- Quentin Crisp

I have now been brushing my teeth in Hanoi tap water for 3 weeks with no ill consequences. This journey could go one of three ways: 

1) Using tap water to wash down my morning vitamins; or

2) Implementation of a similar initiative when I'm in Thailand; or

3) Old Lace (http://news.bio-medicine.org/biology-news-2/Northern-Vietnam-drinking-water-contains-dangerous-arsenic-levels-9565-1/)
