toenails

Do you have to clip your toenails before an MMA fight?

it's like a yellow-green color.. i just clipped my toenails and i realized the discoloration. also, i clipped one of them and there was like, crumby stuff under it. i could pretty much brush it out. and also the nail that had that is like.. dead. i could clip that whole part of my toenail off...

I had an infected toenail a few months ago and it fell off. Now it's growing back, but it's starting to grow underneath the skin at the top (its almost grown all the way back in). Is this supposed to happen?

When I trim my toenails, the smell so crappy. They smell like my gauges. Why do both my toenails and gauges smell like that?

Someone said it is Tom Cruise. I am not sure.

...just hard skin ? help me stop as i can stop biting finger nails
