Hey everyone.

Dr. David here. I'm a NASA trained astrobiologist

0:06

and aerospace medicine researcher and medical doctor,

0:11

and I teach a lot of medical topics like internal medicine,

0:16

like medical, genetics, hematology, cardiology,

0:21

endocrinology, all the ologies.

0:23

But I also teach a lot of basic medical sciences

0:29

and biological sciences like physiology, pathophysiology,

0:33

biology, genetics, even planetary science.

0:38

Because I'm an astrobiologist,

0:40

I've been on television talking about space sciences

0:43

and life sciences, and I just love to help people understand

0:47

and learn new ways to learn.

0:49

'cause it's so important to learn how to learn

0:51

and to do it in a really fun way.

0:53

So you don't need to memorize, you'll only need

0:57

to memorize the bare minimal if you do it my way.

0:60

So let's try out a lesson. Let's, let's get started.
