I’ve gone back to uni this year. I’m taking some undergraduate genetics subjects (code for I feel very, very old sitting amongst a sea of 18-year-olds – appreciate the fact that they weren’t even born when I was last in a lecture hall).
Anyway, when the lecturer introduced the topic of ‘genetic resistance’ and said that head lice provides an excellent example, I quietly thought to myself “In this hall of 300 people, I reckon the only person who might know more about nits than me is the lecturer.” Because, like most parents, I’ve had my run-ins with head lice and nits (technically, lice are the live creatures and the nits are the eggs).
