    I wish my professors had just one percent of enthusiasm for their teaching. they're probably into whatever they're researching, but they don't give a shit about how amazing all of this is for someone who is just learning about it, but no matter how well you know your stuff, you never fail to infect me with your enthusiasm. whenever I have a new incompetent professor I come to your channel to find my passion for what I'm studying again and I can't thank you enough for what you do.

    My brain and behaviour exam is soon, and I'm so grateful to have stumbled upon this video. Thank you so much for explaining this complex concept in a way that I could understand for the first time.

    If I ever publish a paper I'm mentioning ninja nerds in my acknowledgements. The way these videos are helping me to warn the degree!
