Did you know the oldest millennials are turning 40 years old this year? While it’s possible to hit your fourth decade of life without experiencing many, or even any, major medical events, turning 40 may present a new host of medical challenges. Some health issues millennials should start thinking about as they turn 40 include things like kidney stones, hypertension, ulcers and even skin cancer. This is why it’s so important to keep up with your annual physical. Visiting your primary care provider for regular preventative care is one of the best ways to identify and treat health issues before they get worse.
