Let's take a look at a few things I've learnt over the last week:

**Monday:** Three new species of **Opah** were found. **Opah** is a strange creature recently found to be the first fully warm-blooded fish.|![image.png](https://ipfs.busy.org/ipfs/QmdXJJQVYVCL5B9TURkQfsx61EDkvBUbKRYs6PoPC1o7uT)<sup>[Image Source](https://scitechdaily.com/opah-the-first-fully-warm-blooded-fish)</sup>
**Tuesday:** **[3 ETH forks will happen in the next few days.](https://cryptopotato.com/hot-january-for-ethereum-the-three-hard-forks-you-should-know-about)** On **11 Jan 2019** it's the **Classic Vision Hard Fork**. On **12 Jan 2019**, the **Ethereum Nowa Fork**. On **16 Jan 2019** it's the **Constantinople Mainnet Hard Fork**. _(If you keep some ETH in your wallets, you'll receive these coins for free... but in this market where every coin seems to be on a race to Zero, I don't know if holding ETH is a smart move.)_|![image.png](https://ipfs.busy.org/ipfs/QmaavQTtWX6EMESVyYyVQd4zgwDpqi2aC1Gqbx4FtVCLGC)<sup>[Image Source](https://unhashed.com/cryptocurrency-coin-guides/ethereum)</sup>
**Wednesday:** I've found out about a new Musical Instrument, thanks to **@lady-idra**'s post: **[Penumbra Musici - Lur](https://steemit.com/art/@lady-idra/penumbra-musici-lur)**; What is a lur? A **lur or lur horn is a wind instrument cast in bronze dating to the Late Bronze Age** (c. 1000 BC).|![image.png](https://ipfs.busy.org/ipfs/QmcMQ2c2yr4d6WdcKdn2TqJ384yzNC1Qkp8kYXDfAwUqgc)<sup>[Image Source](https://www.dailykos.com/stories/2017/6/22/1673870/-The-Riddle-of-Steel-a-brief-history-of-ancient-metalworking)</sup>
**Thursday:** After years of playing **Red Dead Redemption** on the PS3, I've found out that, while you're riding a horse, the **R2 button makes the horse brake.** How the heck have I played it for so long without using the brakes? Arrrrggghhhh!|![image.png](https://ipfs.busy.org/ipfs/QmexVXdXgi5sJB4SNPTs3UZvNHyKaZHmttgEkVCYBexYSq)<sup>[Image Source](https://www.thumbsticks.com/how-play-red-dead-redemption-1)</sup>
**Friday:** Thanks to the TV program **Орёл и Решка** I've learnt a new word in Russian: **Акула** means **Shark**.|![image.png](https://ipfs.busy.org/ipfs/Qmc8GXXxEyMdo2U55EtQwFRmq2iyogLkouEwS2BuLkX9Dm)<sup>[Image Source](http://expert.ru/2011/08/18/akula-iz-buhtyi-telyakovskogo)</sup>
