Roman numerals were invented over 2,500 years ago. They came from ancient Roman. The Romans were active in trade and business. They had a system of writing, but they needed a way to record numbers so they developed their own system of numbers. That was Roman numerals.
Around 500 AD, a new number system was born in India. It was later known as Arabic numbers because it was largely used by Arabian businessmen and people. Roman popes (教皇) stopped the use of Arabic numbers when the new system came to Europe. They said that Roman numerals were invented by God and were perfect to use. However, compared with Arabic numbers, Roman numerals didn't have a symbol for zero and were too complicated ( 复杂) to use. From the 14th century on, Roman numerals began to be taken place by the more convenient Arabic numbers.
Today, people still use Roman numerals, though not so often. You may find these numbers on some clocks or the front pages of books. You may also see them after the names of kings, queens or popes ( e. g. Elizabeth II ). Sometimes they are used on gravestones (墓碑) as well.

How old is “old”? The answer has changed over the years. Two Hundred years ago, you were old at 35. At the beginning of the 20th century, the average life span (平均寿命) was 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is still thought young.
So, how old is “old”? The answer is one you’ve heard many times, from all kinds of people. “You are as old (or young) as you feel.” Your age simply tells you how many years you have lived. Your body tells you how well you’ve lived.
“Nobody grows old by living a number of years,” wrote a writer. “People grow old when they don’t have their ideals (理想).” People shouldn’t have the wrong ideas about aging. Sometimes, older minds can be as bright as young minds. Alice Brophy once said, “It makes me unhappy when people say, ‘You look young for your age.’ What does that mean? You know you can die old at 30 and live young at 80.”
