Hmm, not sure if I agree that reading can help prevent Alzheimers although it would be great if it's really the case. But so many people whose minds were definitely being kept stimulated by avid reading or by other means have succumbed to this disease and I do think that as no-one really knows what causes it, then we also don't know how not to get it.
My mum was widowed in her fifties when my Dad had a heart attack aged 54 but she kept herself occupied. She loved reading, creative hobbies and playing the organ and accordion. It didn't stop her getting Alzheimers sadly.
I think we can prevent senility by keeping the brain active, I'm just not sure we can prevent Alzheimers in the same way.
I do hope someone can find a way to beat that awful disease soon though.
