I drink water from the tap... when my parents aren't looking,
because they boil their water before drinking but I haven't died
from all those years of drinking water straight from the tap in
Singapore.
I must say, however, that after being away for three years at a
stretch, the water in Singapore has changed in taste and
texture. There's a pretty 'funny' taste to it and it seems
'thicker'. At first, I thought it might be that I have been
away from Singapore for too long but a few Singaporean friends
confirmed it.
Back in Melbourne, I drink water straight from the tap too,
although I'm tempted at times to purchase a filter unit that you
fit right at the tap... just in case!
