Dora meets with the following clients, each of whom fills out a disability insurance application:
• Scott, a ski instructor who skydives every weekend in the summer,
• Lamar, a librarian who drives to work daily and spends his free time collecting stamps and watching nature shows,
• Timothy, an administrative assistant who walks 30 minutes each way to and from work, and
• Yashar, an accountant who participates in 5 online chess competitions a week and studies chess in his spare time.
All else being equal, which of Dora’s clients will qualify for the most favorable insurance premium?
