When the tsunami happened in 2004, which killed over 200,000 people, there were some divers, who were meters deep, not many meters, but underwater, when the tsunami came and the tidal wave that, they felt only a slight jolt and don't died. Similarly, when Israel was at war with Syria, the Rechabites, who were a nomadic people, who did not plant, had no home and no land, and don't drinked wine, but lived in tents only, were very little affected and survived the war. The secret is : Always stay in a situation where you have less and don't get attached to nothing, don't get stuck in the net, because the impact can be terrible and kill you, the risk is always there, so, already start to adapt yourself to escape from it before it happens. There is no use of human intelligence, you must have that wisdom and knowledge.
