It’s summer, when we tan, strain muscles doing yard work, overexert ourselves with outdoor sports, and generally increase our metabolisms. But what’s going on in those little cellular factories that have to respond to our macrobiological exertions? This video gives you some inkling. However, I don’t believe my body generates a soundtrack this spellbinding — even though it would be cool if my cells had some nice music to work by!
