Italy and demographics relevent to life extension / anti-aging-- YTvideo 1/2 hr. VEry good presentation relevent to USA and Canada as well. I found the angle on ageing interesting because if retirement age were raised, a lot of the problems presented solve themselves. IMO I think there is an ECONOMIC incentive to slow and reverse biological ageing.
