Usually ads don’t bother me, I just skip and move on but this show has more ads in its 30 minutes than multi hour shows I listen to, I’ve never listened to a podcast with more ads than this one.
A very informative and educational podcast!
Dr Pam seems goofy and too silly to take a science podcast serious. She regularly doesn’t actually know what she talks about. DEI hire? Broken speech. Doesn’t know her info. Unprofessional and seems to be looking for Crain To fill in her ignorance. Get a real professional. She’s not smart.
Was the first podcast I ever listened to….. and it’s still just as fantastic approaching 800 episodes. Thanks to you both for teaching me so much about something I love learning about so much.
