I’d like to propose a new fad diet: the bear diet. Gorge in the summer, sleep in the winter. Focus on the wild blackberries and apples, the fish, the shellfish, the honeycomb. Lumber about outdoors as much as possible. Roar at people who deserve it.
I can’t promise this diet will lead to a svelte figure but I suspect it might prolong life, and certainly make that life happier.
