Now I'm fully understand why there is such regulation that taxi drivers should be minimum 35 yrs old.

i took a cab yesterday morning and there is this driver who look really young, seem younger than 35yrs old. He wasn't wearing formal shirts (which most cab drivers shld be wearing to look proper), he was wearing this white tight fitting t-shirts and jeans. He's muscular (tat explains y the white tshirt is so tight, he looks like a weight lifter.) and has ear peircing, looks very stylish.

and for that moment i felt threatened and uncomfortable.
Uncomfortable cos it seems tat im sitting in a stranger car which he might drive me to an isolated place and felt threatened cos he's really muscular, even if he were to do anything, i can't fight back. furthermore he's not an old man who looks still full of energy to commit any crimes. ok, i tink im letting my imagination running wild, and also being stereotyping.

Perhaps im juz not used of seeing a man 'seem younger than 35yrs' driving a cab.
