Korean n Japanese youthful secrets

The South Koreans and Japanese have the fountain of youth.I think its their healthy diet,physical activity and non alcoholic n smoking lifestyle.Been reading about a 30 year old Korean influencer and his 62 year old dad who looks more like her older brother. One factor is avoiding harsh UV sun outdoors so i need to buy sunblock n wear my wide brim hat n those U V long sleeves to wear when im driving. im eating sea weed snacks,taking birds nest once a week,putting korean face masks and using argan oil hair shampoo. ive followed the Korean dads diet since my 40s of drinking green tea,avoid sugar n diary,eat brown rice and soba,drink kefir n kombucha and eat blueberry n cherry n red dragon fruit,avocado n grapes.i avoid red meat and now do intermittent fasting.Last nite i drank an almond protein shake,ate lychee n grapes and a hard boiled egg for dinner
