Well, I can't give you the female position except from what they tell me. My fingernails grow rather quickly. My poor brother's are even faster. This can lead to out-of-control nails at times. I'm very mindful of my appearance (in all aspects) and because of past insults, I always keep my nails well-trimmed. Personally, I think they look a lot nicer. Besides, you don't want to be mistaken as a drug user for having an extraordinarily long pinky nail. As for nail biting, noooo, don't do that. Maybe to break it, you could put some foul-tasting substance on them, so when you bite them, you'll be sorry. Eventually, you'll get the hang of not biting. That's the best I can offer.
