Does anyone have an idea on a the first sentence should GRAB the reader in an introduction paragraph? My introduction paragraph is below

There are many reasons why people of all ages are happy or unhappy in life. One of the common reason for people’s unhappiness is obesity. Commonly, obese people have a hard time walking or getting around, can be required to use a walker, cane, scooter, or wheelchair. They also need assistance with taking care of their basic needs. Often obese people snore, experience shortness of breath, have serious health problems, are not able to participate in some activities, are bullied, and live with many other issues which includes challenges like social, emotional, and physical problems in life.
