Spent 7 decades believing I was English. This week, DNA records informed me I'm 41% Scottish and 39% English (the rest a northern European/Scandinavian mix).
Nobody warned me. I've been drinking tea politely and queueing in an orderly fashion my entire adult life. Turns out I should have been doing something else entirely. I could have been wearing a kilt for fifty years. Instead I've been wearing sensible shoes.
Does show me where my undying love of the Highlands and wild, remote places comes from though. It's in the blood
