I spoke to my mum on FaceTime she’s old I saw her face and she actually looked old and tired

My brother doesn’t think about getting a job or studying, he exercises every day but that’s all he does, mum can’t do everything anymore she can but we can’t expect her to , anymore, I’m 36 on Monday and I’m always tired , and at least I have cleaners and gardeners coming to my house once or twice a week well gardener , every three weeks, but she does everything cooking cleaning washing, my brother does help only when he’s told to, I don’t think he realises she’s old , and won’t live very long , she’s 67 in 3 years she’ll be 70
