Sorry the page has stopped working! It was discussing a piece of research showing that grandparents who looked after grandchildren just 1 day a week were less likely to develop Alzheimer's Disease. i will search for a different link.
In term time I have GS2 five days a week and GS1 after school on two or three days. I haven't got time for Alzheimers, I barely have time for a cup of tea!
