Absolutely. From about age 23 to 50 I did absolutely no exercise other than walking and last year I finally took up running and holy cow what a difference. For years i felt like crap, tired all the time, and now it’s like night and day, like getting rocket fuel in the body. Everything has improved 1000% even my hearing which shocked me. Once that blood flow improves, everything is different, everything changes for the better. Every person out there who is out of shape, constantly has health issues or is tired all the time, or is depressed, got problems with sex - Try exercise it will absolutely change your life around I kid you not.
At age 50 I had gall bladder surgery the old fashioned way...with an 8 inch incision. I think they gave me too much anesthesia or something because my heart beats became irregular. That continued until I retired at 57 and took up playing golf 4 to 5 times a week and walk 18 holes. My heart beats became regular, like you my hearing improved, my energy levels improved, sex improved, weight dropped! Now in my 70’s, I am still going strong...I chalk it off to daily walking on golf course or the treadmill at home. I rarely take any supplements, eat whatever is handy, and do not need regular doctor visits.
