How old does somebody have to be to be old? 40 years? 50 years? 70 years? 90? over 100? It’s funny, but when I was a little girl I thought 30 and 40 was old. But when I reached 30 I didn’t think it was old at all. I kept on having more birthdays until now I think 90 is old. The Bible says the first people God created got much older than people do today. Adam lived to be 930 years old
