That's not why he looks old.
It's called genetics.
Same reason i look 10 years younger than my age. Same as my dad and both my brothers.
Nah, so many different components to aging...stress for sure is paramount, diet, lifestyle, exercise, exposure to toxins...I'm 5 years older than my brother, everyone thinks I'm the younger brother. My brother got married young (stress), smokes cigarettes, never been on a diet in his life, rarely gets in the sun, lives in the Midwest, hair is receding and thin. I've been an athlete my entire life, started dieting at 16, took up nutrition courses in college, moved out west at 23, never married, spend majority of my days outdoors, incorporate numerous therapies such as prolonged fasting, ice baths, deep tissue work, iv therapy monthly (glutathione), full head of hear...lots of different things contribute to aging.
