God limited the lives of human beings to 120. No one lives past that. (I know they say one person lived to 122 but if only one did. There may be an error.) Almost everybody who gets to 117 dies before 118. It seems to be a wall.
Also this drug seems to lower blood sugar. With diet and exercise working better. I suggest a low carb diet may do better. Just stop eating sugar and corn anything or flour. Then you get the same affect. You body becomes very good at controlling blood sugar.
Yup, carbs are NOT an essential component of diet, your body can produce needed glucose from protein. The one thing they are good for is enabling certain special humans to feed and manage large numbers of others for directed activities like building pyramids and ziggurats (and modern equivalents) and then having them die off at the age where they become less economically useful.
