Yup, you are getting old!.
but DON"T PANIC
Your life is not over yet.
Aging is not 'lost youth' but a new stage of opportunity and strength.
-Betty Friedan, "Parade", March 20, 1994
Step 1: Take care of yourself
Exercise -muscle tissue can become less flexible, and you lose bone density with age. Exercise can help prevent this, start light , don't overdo it and seek the advice of a physician if you are starting a new exercise regime, just taking a 30 minute walk outside is great.
Exercise your mind -"use it or lose it", it can prevent cognitive decline, do suduko, crosswords, play cards, read, learn new things.
Socialize -surround yourself with friends, humans are social animals and thrive in these situations. Join a book club, knitting circle, play bingo, bridge. If your not big on people, get a pet.
Stay on top of your health, visit a doctor for routine screening such as mammogram, prostate, cholesterol, blood pressure, eye exam, hearing test.
It is also not a bad idea to take a closer look at your family tree, to see if there is any history of illness such as heart disease or cancers that you can take preventative measures against.
You know you're getting old when all the names in your black book have M. D. after them.
Men do not quit playing because they grow old; they grow old because they quit playing.
~Oliver Wendell Holmes
