Wow! It's actually my first time reading a blog that you answered your weekend-engagement concept. I was like, ooh, it seems he's really interested in his topics as well.
Going back to lava swimming, it is absurd to think to go near an active volcano and swim because before you touch it. You'll definitely burn. But with the power of immortality, yeah, you can definitely swim back and forth just like a fire dragon in movies and animes.
How I wish I can travel to the center of the Earth too. That must be the best experience out of all experiences we can have. Hoo! You write this beautifully and you really lived up to your name. Let's go the center of the center! Come on! Just kidding.
I am always interested in my topics but always seem to have something else to write about so I rarely respond to the #weekend-engagement suggestions. I should make more of an effort though.
Trust me, if you ever become immortal you have to do some lava swimming. It's the best thing ever. Lol. Also, if you're ever in the centre of the Earth look me up, we'll go hunt a brontosaurus, make some burgers and hang out a bit.
