John Dionisio didn’t expect to be charting the growth that compounding interest can add to a 401(k) when he signed up for GERO 200, “The Science of Adult Development,” as a USC undergraduate student. But graphing this wealth-increasing investment strategy is a key assignment in the popular undergraduate elective course, which teaches students how to support — and become — older adults. “I did not have any financial literacy before taking this class,” said Dionisio, who graduated as a lifespan health major from the USC Leonard Davis School in 2021 and is now earning his doctor of physical therapy degree at USC. Dionisio says the assignment and the course in general provided a solid foundation for moving to the next stage of life and preparing for changes that come with aging.
That’s exactly the goal and the reason the course is often referred to as “Life Skills.” Taught by Associate Professor John Walsh and USC Leonard Davis lecturer and attorney Julia Walsh, the class covers the impacts of aging from the perspectives of biology, economics, policy, business and society. “Knowledge is power,” said John Walsh. “This course is built on the idea that there is no time like the present for students to make financial and lifestyle decisions that will reduce their risk of many diseases of aging and allow them to lead fulfilling lives where they can do all the things they want to do.” In the course, which is offered online three times a year, the Walshes use personal insights, population data and planning tools to give today’s students tools to be healthy adults. John Walsh shares some of the main lessons with us here:
Start financial planning early
“One of the best things you can do for your future self is to start financial planning now. The reality is that aging comes with financial challenges, whether it’s the cost of caregiving or relying on Social Security. Creating a financial plan, like setting up a Roth IRA, can set you on the path to financial stability. Starting early means you can take advantage of compound interest and feel more secure in your retirement.”
Lifestyle choices matter
“The choices you make today—what you eat, how often you exercise, how you manage stress—can have a huge impact on your health as you age. Things like obesity and poor diet are major risk factors for diseases such as diabetes, heart disease, and even Alzheimer’s. Making small but consistent lifestyle changes now can decrease your risk for these age-related conditions and allow you to keep doing the things you love for longer.”
Take mental health seriously
“Mental health is something we all deal with, no matter who we are or how old we are. Recognizing mental health challenges — whether it’s clinical depression or other issues — can lead to methods that help us manage them. In aging populations, mental health often gets overlooked, but conditions like depression can increase the risk for diseases like diabetes and cardiovascular problems because it disrupts lifestyle. By educating students on brain health, particularly neurodegenerative diseases like Alzheimer’s, we aim to show that it’s never too early to reduce risk. Living a healthy lifestyle today can have a significant impact on brain health in the future.”
Prepare for caregiving responsibilities
“Caregiving might not be something you think about now, but it can be a major part of life as your parents or grandparents age. It’s not just a personal commitment; it’s a financial one, too. Many people find themselves unprepared for the costs and emotional toll of caregiving. Being aware of this responsibility and discussing it with your family can help you plan ahead.”
Have open conversations with family
“One of the most practical things you can do is to start talking with your family — especially older relatives — about their health, finances, and plans for the future. These conversations can be tough but are essential for preparing for what lies ahead. Understanding their wishes and needs helps you make better decisions and fosters stronger relationships across generations.” Former student John Dionisio has taken these lessons to heart and feels that no matter their major, all students can benefit from the longevity literacy that GERO 200 imparts. “Everyone should take this course,” he said. “It lets you know what to expect as you age and gives you the tools to prepare.”
