Bugger Lolli

I was at a burger joint  when I sit done to eat I am facing this man on his computer. Then I see him use his little pinky finger. Going to his nose every 10 seconds and lick that lolli after. I didn't throw up because I have seen this before so I am not surprised. My question is how do the buggers regenerate so quickly, once I clean my nose out thats that for most of the day.
