I could talk for hours on how skateboarding has impacted my life, but Rodney Mullen already did the perfect TED talk on that, and how do you improve on the master?

Seriously, even if you aren’t into skateboarding, watch that one.

I guess two topics I could easily spend a half hour off the cuff on could be “Video conference systems design and best practices for Zoom and Teams call”, or “How to survive a permadeath vegetarian run in Subnatica”.

Then let the audience decide which they’d rather be bored to sleep listening to.
