Heart attacks are most likely to occur on Mondays.
Apparent Paradox
Heart attacks are most likely to occur on Mondays.
The accepted explanation is that because Monday is the first day of the workweek, people feel more stress on Mondays than on other days.
However, research shows that even unemployed retired people are more likely to have heart attacks on Mondays than on other days.
Evaluate
How can Monday being the first day of the workweek explain the greater incidence of heart attacks when unemployed retired people experience the same thing? Could be a legacy factor? If somehow people were influenced in certain ways because they had undergone the stress of those Mondays that might work. Or if the stress of family and friends who continued to work somehow influenced unemployed retired people that might work as well.
