I just finished listening to the six part series on Horatio Nelson from The Rest is History podcast. Great stuff as usual!
The episodes, from October this year, cover his time in Naples, the battle of Copenhagen, and the battle of Trafalgar. Very interesting, can definitely recommend!

I enjoyed the Netflix series "Pretend It's a City" (from 2021), where Martin Scorsese lets Fran Lebowitz answer questions on a range of subjects. Full of witty one-liners, and very New York. Seven half-hour episodes, quite entertaining.
