Dr. Bill Sullivan, TYP regular and author of 'Please to Meet Me' is back and this time we discuss 'discordant twins’ and why having the same genes doesn't always equate to 'identical people'. We also talk about Joe Biden stepping down, why (some) low-income people are among the happiest in, the world, the numerous variables which influence how our genes express themselves, Bill's personal 'health protocol', his love of running (and the numerous benefits) and lots more. Enjoy.
