Recently, pre and 'post' images of Obama surfaced and became popular on various social media networks. It is well known that American presidents age 'fast', in fact research shows a position as head of state substantially increases mortality risk. Using http://how-old.net/, a facial recognition service powered by Microsoft's Machine Learning Group, we investigated the apparent aging rates of the last four presidents. Our work shows that Clinton aged at the greatest rate, 2.9 years of aging for every year in office, and that Bush Senior aged naturally at one year per year. Interestingly, Obama aged 1.1 years for every year in office, just slightly above chronological age.
Aged at nearly three times a 'natural' rate.
Aged 1.7 years per year.
Aged at 1.1 years per year.
Aged at one year per year.
In an effort to test the accuracy and precision of the how-old.net aging tool, we conducted a brief control study. Three 'participants' of a known age were assessed with the tool, Drake, Edward Snowden and myself. As can be seen in the below figure, how-old.net is accurate within a few years for each of the three participants.
