Add to the list of good reasons to go home for lunch:

Beetroot

See your son eat. You will be there to watch your spouse feed a concoction made of beets to your infant son. Observe as he avidly gulps down the ruby-red beetroot smoothie. Congratulate yourself that you are raising a vegetable-loving little boy, not afraid of a little iron and beta-carotene. Then, when you perform the late-afternoon diaper change, you will be marginally less likely to jump to the conclusion that your son has contracted some variety of viral hemorrhagic fever. You can still be alarmed, though, for a split second, by what you see in that bloody diaper.
