oh believe me.. if there's a busy person i know, it has to be her.. she's had operations on her knees because she wore them out from moving around so much.. it was bone to bone already.
She wakes at 3 am, and does house work.. she goes to market at 5 am.. or just goes out for a drive while people are asleep. By 7 am, she's done so much already. And she goes like that till night time. Chasing her around and trying to get her to rest is awfully tiring.
She's 80+ now.
She was even worse when younger.. She was manager of a bank, a PE teacher and a mother to 7 kids. When she gave birth to her last kid, she was cooking lunch, felt like she was about to give birth and walked to the hospital, gave birth, and went back home and finished cooking lunch.
