In the US people are afraid to call for an ambulance because of the cost associated.If you are employed, a yearly medical check-up is mandatory where I live. You must undergo a medical examination before entering employment, so you know where you stand with your health. Perhaps in the US, that isn’t a requirement, leading to these gimmicks.
The elderly and retirees always go for their medical check-ups, as they simply enjoy doing so. Additionally, it is free.
