A normal heart rate is 60 to 100 beats per minute at rest. Ventricular tachycardia is a regular, faster-than-normal heart rate that begins in the heart's lower chambers.
Umami (pronounced oo-MAH-mee) has been called the fifth taste, joining the traditional quartet of salty, sweet, bitter and sour. The word umami derives from the Japanese umai, which roughly translates as deliciousness [source: Umami Information Center]. Chefs have described it as everything from delicate and subtle to earthy, musty and mushroom-like [source: Ninomiya].
Where does the name Japan come from? The name of the country in Japanese is Nihon or Nippon, written æ¥æ¬ in Chinese characters. The characters mean the origin of the sun. This comes from the position of Japan to the east of China. However, neither Nihon nor Nippon sounds much like Japan, so the origin of the word Japan is mysterious. Marco Polo never visited Japan, only China, but in a book he mentions the island of Chipangu.
