The next time you're unkind to your waiter or waitress please think about their health. A new study from Vancouver-based VitalSines took a look at how fast different professions age people internally as compared to their chronological age. They used iHeart, an internal age tracking device placed on the fingertip to measure aortic stiffness. The pulse in the finger helped the researchers determine its user's internal age. And the researchers discovered from studying over 500 people with 50 different positions in North America that those who work in the restaurant industry age faster than any other segment. Servers, hostesses, bartenders, and kitchen employees have been found to be 17 years older than their chronological age. Behind them are talent buyers (at 15 years older) and social works (eight years older). Those with the most positive results include financial advisors, who tested 15 years younger internally than chronologically, doctors (14 years younger), naturopaths (13 years younger), and realtors (eight years younger). 

Aortic stiffness is known as a proven risk indicator of heart and brain disease. But with positive lifestyle choices, such as better diet, increased movement, and lowered stress, this can be remedied. If you want to check out your internal age, you can get the iHeart device at this link.
