I respectfully disagree.The native peoples of Malasia do not get up everyday to scavenge and improvise.They are intimate with their environment, just as we are intimite with ours. They also rely on tool kits, however simple, that are a cultural manifestation of preparation. Ishi, the "last wild north american indian" was the sole surviver of his band. Suprised by prospectors who took the entire tool kit for souveniers, they perished. Improvisation obviously has it's place as does the prescience to "be prepared."
