Speaking of unusual careers. This woman picks lice eggs out of (mostly) children’s hair. She charges $100/hr and it can take her 2-3 hours of painstakingly detailed work to completely remove the eggs from a head of hair.
In case you are wondering why you can’t just use one of those shampoos … the shampoos kill the adult lice but the eggs remain on the hair and hatch later.
If you like detailed work, the market is wide open!
