There are many ways to talk about physical appearance
My grandfather is quite old. In fact, as he has a pension, he is an old age pensioner, or a senior citizen.
His daughter, my aunt, is 55, and middle-aged. She has three sons. One is a young adult, at 24 years of age, and the other two are both teenagers. They are 16 and 17. My sister also has two children – one toddler who is a two-year old, and a baby who is 6 months old.
People are built in all shapes and sizes. There are those who are fat and overweight. Some people are extremely overweight and are obese. Other people are naturally slim, but others look have absolutely no fat on them and are thin, or skinny.
Personally, I am stocky – small, but well-built. My father is tall and lean – with very little fat. My sister is short, but wiry – she is quite thin, but muscular. Both my brothers are athletic and well-proportioned. My mother looks like a 1940's film star. She is curvaceous, with an hour-glass figure.
My grandfather is fit for his age and takes plenty of exercise. He doesn't want all his muscles to get flabby.
My sister is an English rose – she has fair hair and fair skin. She doesn't tan easily and has to be careful in the sun. My mother is blonde, also with a fair complexion. I am a red-head – with red hair. Like many other people with a pale complexion, I get freckles from the sun – small brown dots on my face and arms. In contrast, my father has dark-brown hair and he is quite dark-skinned. You are born with a colour – white or Caucasian, black or Asian. People whose parents are of different ethnic origin are mixed-race. Southern Europeans are sometimes described as Mediterranean.
Faces, like build, vary a lot. Some people have oval faces – their foreheads are much wider than their chins. Other people have heart-shaped, square or round faces.
Features also vary. My grandfather has bushy eyebrows (he has lots of hair!), a hooked nose and high cheekbones. His eyes are large and set quite far apart. My mother has a broad nose, which she hates, as she prefers narrow noses. But she is lucky to have even or regular teeth. My sister corrected her crooked teeth by wearing a brace which straightened them. She has rosy cheeks, small ears and a snub nose, which goes up at the end.
I have long, curly hair, though my sister is the opposite, with short, straight hair. Her hair is fine and doesn't weigh very much, but mine is thick and heavy. My mother's hair is wavy – in between straight and curly. It's cut in a bob and she also has a short fringe, where it is cut horizontally across her forehead. My father is losing his hair – in fact he is going bald, which makes him very sad. My brother looks like he is going to lose his hair too – it is receding.
