At the age of 25, our cells stop regenerating
and start dying...
SO... I have already been dying for 47 almost 48 years... and if it is God's Will, I will continue dying for another 20 to 25 years... or until I am 98 years old...
At the age of 60, I was diagnosed with Non-Hodgkin's "B" Cell Small Lymphocytic Lymphoma (SLL) and 2 years later I experienced a severe heart attack that I did not feel while walking on the treadmill except for a sharp pain in my chest. I tried to duplicate that pain by walking as fast as I could on an empty stomach on the sand at Myrtle Beach but it did 
not happen. An exploratory heart surgery a few months later revealed that I had 3 blocked arteries: LAD 100% and two other left side arteries 90% each. It was recommended that I have a triple bypass but I found a cardiac surgeon at NY Presbyterian Hospital who cleaned out my arteries and inserted 5 stints by performing 3 surgeries over a 12 month period of time.
At the age of 67 and probably because of my Lymphoma chemo treatment, I was diagnosed with Melanoma and it was surgically removed with ABSOLUTELY NO follow-up treatment at all which was the PROTOCOL for the stage of my Melanoma. Almost 5 years later, my Melanoma migrated from my foot to my groin and later to my neck. 
Shortly after this second diagnosis, I was taking a cocktail of 2 drugs that eventually led to dropping one of those drugs and replacing it with 6 doses of concentrated and strong radiation.
At the age of 72, it was discovered that I had a hyperthyroid which was causing most, if not all, of the side effects that I had been attributing to my cancer(s) treatment. It was also discovered that my PSA numbers had double and have been seeing a Urologist who is considering performing a biopsy of my prostate.
It would appear that old age and cancer has been trying to hasten my dying process...
