перевидите как можно точнее- My sister's a swimming instructor. As you can imagine,she's as fit as a fiddle, but my brother,who used to play rugby every weeked,is now out of condition-he musthave put on 20 kilos in the last two years. Finally,there's my granddad. He's nearly eighty but he's got lots of energy. He plays golf three times a week and jogs around the park on the other days!
