Three cheers for Professor John Zimmerman, who's finally doing some research to benefit Joe Public, and who has invented a device that lets parents sleep in late and put the kids to bed early on those long summer days.
But we also rely on a certain order in our lives, a certain sense of security that lets us sleep safely in our beds and walk around our neighborhoods free from fear, and go about our daily lives without being the victims of crime.
Riding the gyrations of the stock market up and down does not come without a certain amount of thrill, but many investors would gladly find another place in their lives for thrill-seeking and opt instead for an investment portfolio that lets them sleep at night.
