I can get by without deodorant, my sweat doesn't stink unless I'm really sweaty and if I'm in a situation where I'm that sweaty typically deodorant doesn't help much.
The lack of shower was easy enough to get past with baths which aren't as good at cleaning as a shower but would be worth it.
The lack of brushing though... Not sure how to get around that, it's a real problem because it's not just a breath stinking issue but also something that will directly impact your health.
The commercial says that Church isn't for perfect people, I guess that's why I'm an atheist.
