What could you tell your cousin to cheer him up? Does everything in life get worse with age?

The first question is about “teratogens” and I have included pages 427-430 (in color) for answering this question.

Question 2 is about Adulthood, and I included pages 456-462 (in black and white) for answering that question.

QUESTION 1
One of your friends recently got married, and she and her husband are planning to have children. You mention to your friend that once this happens she’ll have to stop drinking. She scoffs. “They make it sound as though a pregnant woman who drinks alcohol is murdering her baby. Look, my mom drank wine every weekend when she was pregnant with me, and I’m just fine.” What is your friend failing to understand about the effects of alcohol on prenatal development? What other teratogens might you tell her about?

QUESTION 2
One of your cousins has just turned 30 and, to his horror, has discovered a gray hair. “This is the end,” he says. “Soon I’ll start losing my eyesight, growing new chins, and forgetting how to use a cell phone. Aging is just one long, slow, agonizing decline.” What could you tell your cousin to cheer him up? Does everything in life get worse with age?
