Not too easy. Not too difficult.
For one, Altena is a great professor. He knows his subject and he's passionate about it, which I think make the best teachers. The class isn't so hard that it stresses you out, it does however give you enough challenge to make you think. If you show up to class, LISTEN, and do your work diligently you will succeed.
Altena is a comedian and I would take any classes he offered and I learned most of all that information is not enough for people to change their habits. You have to give them motivation or create it in their life.

Advice for students:
Attend every class, it's mostly a lecture class. You learn the most from the in-class discussions and the rest from keeping up with stats about America and its unhealthy lifestyle.
