I think that's the obesity solution right there... I think we should be throwing live fatties in, but we could warm everyone up by having obese burials at sea first. Reduce the pressure on burial plots, reduce the risk of crematorium fires, cheaper for the families and the sharks would get fed so there'd be less attacks on the living humans using the water. They could calculate the best 'burial' locations by tracking the sharks which they are increasingly tagging with gps.
