Back in the 1800s, composer Franz Liszt was worshiped like a rock star. In fact, he received so many requests for locks of his hair that he eventually bought a dog, only to snip off patches of its fur to send to his admirers.

For a few years until 2016, if you want to buy dollars in Argentina to travel abroad, you needed to send an application to the government declaring where, when and why you are traveling.

Wolves are legendary because of their spine-tingling howl, which they use to communicate. A lone wolf howls to attract the attention of his pack, while communal howls may send territorial messages from one pack to another. Some howls are confrontational. Calls may be answered by rival packs. Much like barking domestic dogs, wolves may simply begin howling because a nearby wolf has already begun.
