I just read the book and I have a question about the wrinkled/ tight test. I got a score of 41 which is on the borderline of wrinkled. The test has 6 questions asking how old your parents and grandparents look, respectively. My issue is all of them have been heavy drinkers and smokers throughout their lives besides my mom when she was pregnant with me. They also loved the sun. So they look older than they are but some siblings of my parents look a lot younger than they are and they did not drink or smoke. I think their aging has to do with more environmental factors (how they took care of themselves) which would not have anything to do with my aging ( I was not exposed to the smoking either) The numbers for them made my score go up a lot. Which skin type do I follow. Any suggestions? Thanks
