I'm not saying self-maintenance == attractiveness, I'm saying that no matter what industry you're in there's some minimum level of something you need to maintain to be acceptable for work.
For me as a syseng that's getting enough sleep, staying ahead of my field and basic hygiene. I'm not in the best health but I'm also not in a position where I can get a lot of people sick.
I'm overweight and as a result my skin is terrible. Not so much that people notice but I certainly don't think that I should have my hands in anyone's food.

I'm reminded of the time I waited 90 minutes on line for Shake Shack (original location, when it first opened) and as I got closer to the front saw that the cashier had a visible and severe herpes outbreak that looked like it wasn't being treated. She kept scratching at her face and then touching peoples' money.
