Feel old yet? Here are some of the biggest "adulting" concerns according to a new study

A survey polled 2,000 Americans about all the parts of life that make them feel old and found that the top sign they knew they were an adult was when they finally had to think about saving money (35%). Conducted by OnePoll and commissioned by Fabric, the survey showed that more than half of Americans (51%) feel like they're off track of where they should be in life, in general — with 39% feeling like they're being left in the dust by friends.
