63 to 95 years old? Hell, the first month I moved cross-country (at 22) I got really, really sick and couldn't get out of bed to buy groceries. After the third day I considered asking my estranged dad (who I was getting away from) to fly cross the country, or asking my landlord for help, or calling the hospital or 911. I literally had NO idea what to do. I wasn't dying I just couldn't stand up without barfing or getting dizzy.
It was incredibly scary for a young kid trying to find a job and start a new life. I immediately saw the value in the door-to-door checkup services for the elderly.
