Jackie McCarthy did all the right things to take care of her body. She tried to eat right, exercise, and listened to her body. She had known for several years about her mitral valve prolapse and heart murmur. But when she noticed shortness of breath and fatigue after she exercised she knew something was up.

She was told over and over again that her symptoms were "normal" and she started to wonder if she was being overly anxious. When her symptoms did not improve, her doctor suggested she see a cardiologist. She began to see a cardiologist every six weeks and her physician's assistant closely monitored her visits. After a year, she was advised to seek a second opinion.

After more testing, it was discovered that her mitral valve prolapse was in stage 4 and surgery would be required. The surgeon found a hole in her heart and ten pounds of fluid was drained during surgery.

Jackie McCarthy is here to say that you must be your own advocate when it comes to matters of the heart. She thanks God every day for healing her heart. Hear Jackie's story on Shaped by Faith On-Demand.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
