What are the greatest achievements of mankind?
I concider jeans the greatest achievement of mankind. Levi Strauss a young German pioneer when he came to California in 1848 he wanted to sell tent for miners. But one day a miner said to Levi „What I need is not a tent but a pair of strong trousers”. Levi had an idea.
He used very strong cloth to make his first pair of trousers. It was later called jeans. Can we really imagine world nowadays without Levi’s invention. I bet everybody has a pair of jeans. I think jeans are the mot comfortable cloth I have ever had. Everyone like wearing jeans.
