I am an African American student currently attending NUS.
I occasionally go on jogging runs, and today I actually decided to do a little running outside and inside the school.
Needless to say, I usually jog without my shirt.
I looked online (variuos sites that are Singapore related, and came to the conclusion that there was nothing wrong) However, one of my acquaintances today told me it was 'indecent exposure' in Singapore to jog without a shirt...and I told him he was the first to say so.
Just out of curiousity, I was going to post my question on some of those other Singapore related forums, but I wanted to (hopefully) get this mystery solved since I've actually heard different things.
Thanks...
EDIT/UPDATE: Alright, a text message from the study abroad liason at NUS said 'I can' run, but it's not considered nice; and not so many do it so it becomes an attraction.
(I told her that I didn't mind the attention!)

So, now I know.
