Not as old as a few of you folks but I was alive when Kennedy got shot riding in his car in Dallas.
I am on Hypertension meds, cholesterol - non statin (statins fuck with me), and daily dosage of Tadalafil for BPH.
About a month ago, I started the Heart Healthy Diet. Pretty simple, Half your plate is Vegetables and Fruit (concentrate on Vegetables), 1/4 grains and 1/4 protein. I manage to go without meat for dinner at least once a week. I quit salting things and I have managed to start eating more salmon and less red meat and have dropped fried foods. It's been a pain in the ass since we are cooking on most days instead of grabbing fast food a 2-3 times a week or Flautas from the bad ass cook on my block. That being said...
I have fewer aches and pains. I do have a nagging groin injury from a fall I took in December but I can get off the floor and sitting positions with more ease these days. Also my BP has been like 145-160/90-100 range every doctors visit up until yesterday when it was 117/67.
I went for a walk this afternoon and my resting HR was in the 50s at some point.
tl;dr -It's not too late to start eating better. It is a good thing and can do your body all kinds of good. I am hoping at some point I can get off all of my prescribed meds.
