Do grown-ups still grow? Well, some parts of a grown-up's body do not grow, but some do.
Grown-ups cannot get taller. The bones (骨骼) of their arms, legs and neck lose the ability to get longer. After the age of 30, people start to become a little bit shorter. They will have lost about two and a half centimeters of height by the age of 55.
Meter your height when you get out of bed in the morning and then again before you go to bed that night. You will be a little bit shorter at night because during the day, your cartilage has got pressed together. When you sleep, the cartilage opens up, and you are taller again in the morning.
Grown-ups can grow bigger muscles (肌肉) if they exercise and if they eat healthy food. Riding a bicycle or running a lot will make leg muscles bigger. It's best to do some exercise for all the muscles.
This is also a kind of growth, but not a healthy one. The best way to grow healthily is to exercise often and eat a lot of different healthy foods.

E.Eating lots of fatty and sugary food can make adults and children put on weight, too. F.They get shorter because the connections between bones, called cartilage (软骨), get pressed together. |
