The document summarizes interviews with three individuals about their daily walking habits:
1) A Stanford student who walks everywhere on campus due to past biking accidents and finds it more convenient than other modes of transportation.
2) A Berkeley student who walks 15 minutes each way to campus from her off-campus apartment, viewing it as daily exercise that she does not mind.
3) A mom who takes a 30-minute walk after dinner each weekday with her husband and dog, and longer walks on weekends, as a way to spend time together as a family and exercise the dog.
