Buildings' primary purpose is to provide a private space where one is able to work in peace without being interrupted by others. Words to remember include safety, security and privacy. The social purpose of buildings is to create environments and areas where individuals can perform their activities optimally.

Bitcoin operates independently of central banks or governments. It's a peer to peer software and cryptography. Anyone with a spare PC can create one of these servers, called a node. This consensus is not based on the trust of a single source, such as a bank, but rather on cryptographic means. Every transaction is transmitted and shared across all nodes. Every ten minutes or so the transactions are gathered by miners to form a group called a block and forever added in the blockchain. This is bitcoin's official account book. Like you would keep the coins you have in your the physical wallets, virtual currencies reside in wallets made of digital that can be opened by client software.

The source of travel has been lost to history. It could have come in the Old French work, or work. Merriam Webster claims that travel's first usage was noted in the fourteenth century. The Merriam-Webster dictionary also says it is derived from Middle English travelen and travailen (which means to torture or work to achieve a goal (or journey) in addition to Old French travail (which meant the effort required to complete the task at hand, do hard work or work hard). In English it is still common to hear travail which is an effort. Simon Winchester's The Best Travelers' Tales from 2004 declares that "travel" as well as "trouble" each have a more ancient origin. The tripalium, which was a Roman instrument of torture is the root of these words. Modern travel may or may not be much easier, depending on the location. The journey up to Mount Everest, the Amazon rainforest, extreme tourism, as well as adventure travel are among the most complicated kinds of travel. It can be even harder if you travel in a different way, like via ship, bus, or even a bullock carts.
