now,she can liveuntil at least 80. One of the main reasons for people living longer is that weknow how to look after ourselves better. We know which foods are good for US
and what we have toeat to make sure our bodies get all the healthy things they need.We know why wesometimes get ill and what to do to get better a-gain .And we know
how important it isto do lots of exercise to keep our hearts beating healthily. But in order thatwe don't slip back into bad habits,let's have a look at what life was like 100
years ago. Familieshad between 15 and 20 children,although many babies didn't live long. Childrensuffered from lots of diseases, especially rickets (佝偻病)and scurvy
(坏血病),whichare both caused by bad diets.This is because many families were very poor andnot able to feed their chil-dren well. Really poor families who lived in
crowded cities like
until the 1920s.Theykept fresh food cold by storing it on window-sills(窗台板),blocks of ice , or even buryingit in the garden. Some children had to start work at the age
of seven or eight toearn money for their parents. If you had lived 100 years ago, you might well beselling matchsticks(火柴杆)(ajob done by many children) or working
with your dad bynow.
