Do professors procrastinate?

Ok so I'm a master student and graduating in two weeks. I need to admit that I procrastinated A LOT during working on my thesis. If I do my PhD I expect myself to procrastinate a lot too. However, I'm wondering if this habit vanishes as the individual gets more senior in academia. So maybe as the person gets more senior in academia he learns to handle this habit quite better.

My questions:

1. 
   

   Is true that the more senior you become the more you are able to handle this bad habit?

   
   


2. 
   

   Do professors procrastinate too?
