I quit booze, went on a diet and took vitamins for a month – what did it do to me?

This might sound strange but, I promise you, it’s true: until this year, I really hadn’t given my health a second thought.

I say that from the outrageously privileged position of being a 37-year-old woman with no major health issues thus far. I’ve never had an operation, spent the night in hospital or so much as broken a bone. Heck, I can count the number of times I’ve needed antibiotics on one hand.
