11. You Start ‘Shrinking’ at Age 40

It’s no secret that adults grow shorter as they age, but it may start earlier than you think: Both men and woman may begin slipping in stature as early as age 40, decreasing by half an inch a decade, says John Whyte, MD, MPH, chief medical expert and vice president for health and medical education at The Discovery Channel and author of Is This Normal?
Behind the shrinkage: the discs in your spine, which lose water and begin to compress over time. Osteoporosis, a bone-weakening disease that affects up to 10 million Americans, can exacerbate the problem.
The good news is that working on your posture may help counter height loss. “One of the most important aspects of maintaining height is proper posture,” Sinett says. Stretching, strength exercises, yoga, and working with a chiropractor or physical therapist can help.
