Aging...

I attended a funeral for a previous employer last week.

While he was 77 years old, we all thought he was in great health.  He played golf and tennis several times a week, ate well, spent time with his children and grandchildren. 

His son found him dead in his home of a heart attack.

A month ago a fellow Rotarian was found unconscious in his back yard by his daughter.  She started CPR on him and brought him back.  He is 60  years old, semi good health, exercises.  He had a heart attack.

Two weeks after that another friend went to the emergency room with chest pains.  Heart attack.

I am looking at all these heart attacks in just the past month and I am getting a little frightened. Is this what happens when you get older?  All your friends start having health issues and dieing?  Is it ever too late to try and change your lifestyle?
