Semenza, of course, freaks me out.
If you have no idea who this man is, let me explain: Semenza has written a book about graduate studies that demands that you:
-take no more days off than either Christmas /or/ Yom Kippor. That's it.
-read 100 articles a week for each seminar
-publish 30-page articles every semester
-never see your family if possible. If this is impossible, make them visit you in the library. Between page-turning.
-create several folios and vitaes
if you don't want to end up homeless, addicted and, eventually, murdered in cold blood.
Hurrah for academia!
