I suggest reading the book by Steven E. Landsburg, 'The Big Questions, Tackling the Problems of Philosopy with Idea from Mathematics, Economics, and Physics'.
In Chapter 13 on page 123, he wrote; "Thoughout the year 2004, the one million residents of Benares, India, went through about six hundred thousand condoms a day. Most of those condoms, (provided free by the Indian government0 were used not for family planning or disease prevention, but to lubricate the city's two hundred thousand looms. Weaver too the free condoms, rubbed them on the loom's shuttles, and discarded the latex."
This is a VERY good book and the chapter I wish every one would read is the chapter titled "How Big of a Jerk Are You?
