I will be 70 July 10th. I smoked 3 packs a day for 35 years and drank to get drunk many days in my 20's and 30's. I retired to Florida ten years ago. I played on a softball team for 5 years, also pickleball and golf. Then in 2016 I had pneumonia and afterwards I couldn't run to 1st base without being out of wind. I saw a pulmonary doctor and he said I had emphysema, so I had to give up softball and pickleball.
I could give you a list of ailments, the worse was in 2017 I had Lymphoma and they removed 3 bumps under my armpit. I have to take cholesterol medicine because I have a stent in my heart, but I became allergic to the pills (statins). They gave me new drug instead, it come in a needle and I have to give myself an injection every two weeks in the stomach. That was fun the first time, sticking a needle into your own stomach.
Overall I feel good. Go to the gym 3 days a week and lift weights and walk the treadmill and play golf every Friday 18 holes, I ride a cart of course.
I would say, take care of you health while you still have a chance. Don't smoke, drink moderate, maybe get drunk just once every week or two. Definitely workout with weights and cardio on the treadmill or walking/running.
That's me second from the left in 1979 (age 29), I was pretty drunk that night, it was a Christmas Party.
Here I am now with a computer photo, a week shy of 70.
