I agree with the rest in that it is not a good idea but if you need root 
and don't want to leave the vulnerabilities open after your session then 
simply do:

    sudo su -

which will activate root via your user and go away when you log out of 
the terminal.  This does not create root nor does it make a permanent 
change to your user but comes in handy if you are going to do extensive 
root work.
