I think this guy, and most people like him, need to accept that the people who look really young for their age largely look like that because of genetics. My aunt is 71, overweight, lives in turkey, and although she spends a lot of time indoors bc she has agoraphobia, she never wears sunscreen (she does dress modestly and wear a hijab tho). She passes for early 50s easy with her hijab covering the white hair. My mum is similar, she even smoked at uni and isn't an agorophobe, but at 61 with hair dye she looks early 50s, and can look mid 40s with some light makeup. My dads side are similarly blessed. I will say that my dad had a full head of hair in his mid 50s, the he went vegan and rapidly developed a small bald patch, which even after reverting back to being an omnivore still hasn't gone away, but it hasn't grown. If you don't have good genetics your best option to look young is plastic surgery, but thats it. Being a turk i know tons of smokers, but the ones with good genetics look great in middle and old age, and the ones who dont have that look rough, so smoking isn't the biggest factor here.
