More miracles

A Tibetan woman in her eighties was salvaged by rescuers with the PLA's No.536 Hospital from the rubble near central plaza of Gyegu Town at 4 p.m. Friday, 57 hours after the quake.

The old woman's legs had been broken but was recovering well after medical treatment, according to the hospital's rescuers.

Huang Jianfa, captain of China International Search and Rescue Team, told Xinhua that emergency rescue operations around the world have proved elderly people and females have more chances of survival in earthquakes than young people and males, since they are generally mild-tempered, which helps preserve body energy beneath the debris.

About the 72-hour prime time for rescue, Huang said this was estimated by statistics gained from previous earthquake rescue operations and the human body's physiological limit.
