[quote name='Clak']Hmmm, would a zombie FDR still be crippled from polio?[/QUOTE]
In theory no, physical ailments (aside from the shamble caused by a missing leg) seemingly no longer effect a zombie. In reality, he wouldn't be crippled by the polio since the disease wouldn't have the correct flesh upon which to feast and manifest, however he may still have the resulting physical ailments (brittle bones, malformed muscles) that could cause some difficulties in ambulation. All in all, he'd be a slower slow zombie.
I wonder if Usain Bolt could be an "infected" type fast zombie, while still being a slow zombie strictly because of his living physique and muscle memory. That's some interesting shit there.
