Actually, you can sudo -s to get a shell with root privs. I typically use sudo -s -H.

Also, sudo -k will kill your timestamp, requiring you to enter your password the next time you try a sudo command.

sudo is almost infinitely flexible. Changes to the behavior of sudo can be affected through the /etc/sudoers file.
