"People retire in different parts of the country and they don't live near their extended family," he said.
"Saga Zone is good because it will engage older people with another technology.
"But that generation will never stop eyeball-to-eyeball contact because that is what they are used to and that's what they like to do.
"And I hope for all of us we don't abandon face-to-face communication.
"Even in offices you see people e-mailing one another three desks down - crazy stuff."

"Saga Zone is a place where they can mingle and chat about issues important to them, be they amusing or serious."
