Another example. Apparently when you run, you should try and land on the soles of your foot. I've always thought you should land on your heel. Maybe if someone had imparted this knowledge to me earlier in my life, I could have been an Olympic sprinter, or a marathon runner. And then narwhals. Do you know about narwhals? I didn't.
I was introduced to narwhals by 11-yo, who sings a song about them. (You need only listen to half of this - it just repeats. Go on, it's only 30 seconds of your life, and there's only one rude line. And it's not even that rude. Unless you count the word "kick-ass" as rude, in which case there are two rude lines. Oh, just listen to it and I'll stop apologising.)
It seems that narwhals really do exist, in the Arctic. They are whales, who are notable for their one long horn, which can be up to 3 metres long. Only the males have horns. I don't know why I never knew about narwhals. Maybe they're not real and wikipedia is having a laugh.

Did you know about narwhals? Did you know the narwhal song? Have you learnt anything else new recently? In your own personal accent, does 'narwhal' rhyme exactly with 'firewall'? So many questions.
