How to look younger:
1- Healthy life (sleep, good food, clean drink, exercise)- too much time.
2- Having a satisfactory and preferably well paid job, hobby, or profession - too much time to spend to get there, to have a distinctive body proportions, an overwhelming passion, or brainy. (no guarantee to look younger, but it works for some people)
3- Having a natural late ageing metabolism. (some people have it, not necessarily being a celebrity)
4- Make-up, anti-ageing products, plastic operation, and good camera light- too much time and money required.
5- Praying or working for anti-ageing science, such as cell repairment, cloning human organs, etc. -most reliable and efficient way in the long term. You can live 250 year with the body of 25 years old. Perfectly human dream.
6- Staying out of stressful conditions -you shouldn't worry even if your city is destructed by a tsunami, hurricane,earthquake, or you shouldn't care if your daughter runs away with a junkee. Stay calm, like nothing's really matter.
7- Praying or working for artificial simulation of human brain in a software environment. So you can choose your body and socialise with other simulations. (Requires a great leap in computer technology and the science of human brain)
8- Living in a society who does not give too much emphasis on age related issues -you don't get younger, but no one looks at you as too old either.
