Dr. Amy Shah on Instagram: "If you’re living in the second-half of your life, thinking that you are at a dead end— I want to share with you the science. You can elevate yourself at any age. It’s even possible to reverse the age of your heart (with exercise), your brain (with magnesium, exercising, abstaining from alcohol among other things), your muscles (through weightlifting, adequate protein) and so much more. Life does not end at 25. I wish more people knew this."
