Tom is an egomaniacal narcissist to the extreme. Beyond the millions spent on surgery, fake teeth, fillers, hair transplants, dye, etc., Cruise doesn’t smoke, drink, do drugs, and he’s endlessly following strict diet and exercising out the wazoo.
Add in he does have quite good genetics.
I’m 48 and most think I’m late 30s, max. Not bragging. But I, too, have never drank (never even been drunk), smoked, done rec drugs, or indulged in much “night life”. Never been married, either. And I have been consistently weight training since I was 15. I am MUCH heavier than I’d prefer to be, but it’s by design, as I am still chasing absolute strength, drug-free.
Just making the point that ... decent genetics and a disciplined existence goes a long way to put one in better stead come the mid-to-later years.
As another says, booze and smoking alone is devastating to the body.
