I don’t think that people necessarily age faster than they more or less look like they are aging for example some people look older than they actually are. To answer your question as to why that could be well in my opinion it has a lot to do with how well you take care of yourself by eating healthy and exercising on a daily schedule although it won’t stop you from getting older but could help in the process of slowing down the look of old age in other words if you do it right you will look and feel young for a long time to come.
