Back pack and duffel bag - I have lived in 2 bags for 20 months now. In the winter of 2016, I removed most of my clothes. What is suitable for two packages? 2 black pants, 6 black T-shirts, 1 pair of sweat pants, 1 sweatshirt, 1 jacket, and 2 pairs of shoes. Every morning I reached for my luggage pants, pair of pants, T shirt and some underwear, I was ready. The wardrobe you carry with you makes life easier in many ways. really. Everyone says it is bad, but that is not as bad as it sounds. My body is very small. I think that I am one of the lucky people. I participated mainly in this experiment and confirmed the time when I can not take a shower every day and how to use extra time for those I care.
In the modern world, bags are everywhere, many people carry various bags in the form of cloth and leather briefcases, handbags, backpacks, and made of more disposable materials (paper and plastic etc.) I will. The bag is used for shopping and carries domestic groceries. The bag can be closed by a zipper, a snap or the like, or simply by folding (eg in the case of a paper bag). Your wallet or travel bag may be locked. Bags may be faster than nonflexible variants, and baskets and bags are usually more advantageous than collapsible or smaller size compressible baskets. On the other hand, baskets made from harder materials can better protect the contents.
From the 19th century to the 20th century, bags were designed to suit specific uses (school backpacks, hiking backpacks, travel suitcases). In 1938, a zipper was added to the bag. Nylon backpack was first sold in 1967. Despite these improvements, the shape of the bag remains essentially unchanged. Innovators spent all the time trying to repeat the same subject a little. That is exactly right. We have a flying car. They are called airplanes. People who raised problems ignore that function (by air transport) as they concentrate on that shape (which looks like a thing that is flying in the car). This is what Erron Musk said, and he often said people often "live life with analogy".
