If your brain is burned up or eaten by worms the information that was in it may in some sense still exist but there may not be enough energy in the observable universe to extract it and make use of it before protons decay in 10^35 years or so destroying the physical universe and making all further computations impossible. However if my brain has been frozen in liquid Nitrogen it would take astronomically less time and energy to extract the information in it than it would with your worm food brain or burned up brain.
