So we are told, “beekeeping age” refers to attractive men around 40 or 50 years old, intended as a compliment. Given that I am waaaaaay past my beekeeping age, and the source of this wonderment is Tik Tok, this new learning amazes me.

Anyway, I always refer to beekeeping age as the number of hives each year multiplied by the number of years. For example, if you keep three hives for two years and then four hives for the next three years, your beekeeping age is 3x2 + 4x3 = 18. For me, that makes sense. A commercial beekeeper like Stewart Spinks with several hundred hives is likely to learn and know more than a hobbyist with three hives, so Stewart's beekeeping age is perhaps 200x10, ie 2,000. And that, of course, is his actual age, too.
