Anyone remember this story from 2004?

A mother has spoken of the moment when she realised she would have to choose which of her two children might die.
Jillian Searle, from Perth in Australia, was on a family holiday with her husband, Brad, and sons Lachie, five, and Blake, two, on the island of Phuket. The tsunami struck as she and the children were strolling past their hotel pool.
As the waters rose she grabbed them but soon knew that she would not be able to hold them both. "I knew I had to let go of one of them and I just thought I'd better let go of the one that's the oldest,"
Of course any other culture, than a Western one, would scarifice the baby and keep the child who had already got past the infant mortality stage. That would be the normal instinct.
This hypothetical end-of-the-world-as-we-know-it scenario that this thread has mutated into: Im afraid old people are expendable as are children. Survival of the best fitted to adapt to new surroundings would be needed to start a new society. Intellect wouldnt come into it; brute strength, hunting and breeding ability would ensure the survival of the species.
