It was a bit of humour

I don't know if its healthier or not. It definitely looks cleaner and its one of those distinctive things I still do... not because I'm a believer, but just because I like it. Girls sure enjoy it.
Overall though, Islam did emphasize cleaniless. Not sure how that translated to most Muslims, but when I was a kid, there were all kinds of sunnah we had to do that I think were clean. The obvious ones... but also things like1
1. Never standing and eating. Always sitting down.
2. Don't stand and piss. Sit down and clean yourself properly. Now... this one is probably not as clean, as you're sitting on a toilet seat... so you better use a barrier
3. make whudu throughout the day
4. smell nice
5. trim your nails... long nails make you look feminine
...
Yep! This is what I was talking about. But some people here could not swallow the fact that, out of their extreme hatred for the religion that they left. Being an ex-Muslim doesn't mean we have to joind the bandwagon of haters.
Islam does emphasize on cleanliness. Shaving pubic and armpit hair, use water for anal and penis cleaning, etc. This is one thing that we should compliment Muhammad for.
Is it true that the Hindus of India took care of cleanliness due to long rule by the Moghul Dynasty? I mean, their language, Hindi, was formed during the Moghul, otherwise, they will still be speaking Sanskrit now. If essential element such as language was transformed, I think their hygienic lifestyle can be too.
The Hindus( southern one) that were not directly influenced by the Moghuls lacked in taking care of cleanliness, as I observed.
