Ok so I was watching a documentary about pigs today (I was terribly bored), so I found out that pigs actually don't sweat. Really surprised when I heard that, they apparently are not born with sweat glands so they do not have the ability to sweat.

Today I started watching an interesting new documentary series on the great Paul McCartney.
I learned that he got to see Jimi Hendrix play live in the mid 60s.
What an amazing time to have been alive.
I would have loved to see these legends just doing their thing in swinging London.

I learned how to relay a tile in my kitchen. A workman in my house showed me how to smooth grout & lay a tile to replace one that was cracked. I’m not really much of a manual guy so it’s a good tip that I will probably have to repeat at some point in the future.
