Quotes of the Day

Sleep itself has 3 important phases. The foundation state is light sleep. Deep sleep is our most restorative sleep but you have to pass through light sleep to get there. The third kind of sleep is dream sleep (REM sleep). Dream sleep is when the vast majority of dreams occur. Light sleep is the doorway to both deep sleep and dream sleep. It's not common to go from wakefulness directly to dream sleep or from wakefulness directly to deep sleep. Furthermore, it's uncommon to transition directly from deep sleep to dream sleep. Doing so can be a clue to determining what's wrong with someone's sleep. [2017] - W. Chris Winter

Only buy certified rare coins. A coin graded 70 is flawless, as if fresh from the mint. Coins graded between 60 and 70, representing their good condition, are regarded as being "uncirculated" and in "mint state". [2008] - Shayne McGuire
