One of my favorite people to watch is Theo Von. I watch all of his videos. He is a comedian, but he also has his own podcast where he talks about his life, gives advice to people who ask him about things, and he also interviews people. Interviews many comedians, actors, musicians, and also interviews just regular people who have some job that people may have questions about.
One of the interviews he did was with Frank Giles who is a mortician. So he explained what the whole process is like, and what some differences are between different ways that these things can be done.
