Relax. You’ve been through this before.
Back when you were a baby baby boomer, your doctor probably laid you down every few months and measured your height.
Then came the big day: you toddled into the doctor’s office on your own two feet and instead of lying down to be measured, you stood up. And the odds are that when the doctor jotted down your height, it seemed to suggest that you had shrunk since the last visit.
