What does your hair have in common with turkey?
They both contain a chemical called tryptophan. Tryptophan is one of the amino acids that make up the protein structure of hair. It is also easily degraded by UV radiation so when scientists measure sun damage to hair, they can measure how much tryptophan is lost.
Hairy turkey
Ok, that’s mildly interesting, but why is hair related to turkey?
Because tryptophan is also found in turkey. In fact, it’s the chemical that people claim is responsible for making you sleepy after a big Thanksgiving dinner.
Except that’s not really true. Snopes.com has an excellent debunking of the turkey-tryptophan myth. While it IS true that some forms of tryptophan can be a natural sedative, the kind in turkey (and many other meats as well) doesn’t make you drowsy. So, if you doze off after a big Thanksgiving meal, blame it on too much wine and mashed potatoes and not the tryptophan!
Giving thanks
And finally, since today is Thanksgiving here in the US, we’d like to thank all our readers for their continued support. Without your questions we wouldn’t be able to do this blog.

Lol, adorable post! Where do you BBs find all the kooky pictures? hahaha
@Vinia: I’m glad you enjoy the pictures we pick for our posts. We always try to come up with something off beat to entertain our readers. But no matter how “kooky” the picture is, it ALWAYS has some connection to the topic of the post. Sometimes that connection isn’t obvious, but it’s always there!
