If Bolt, Tyson or Asafa continued running into there early to mid-thirties, does anyone believe they would progress (run faster) or do you think there performances would diminish at that age?, considering they maintain focus, desire, drive, dedication etc?.

Does anyone believe the WR could fall even further from anyone of those guys around that age bracket?.

Yes, but I believe that the critical factor is will they be able to maintain their will power to do such a thing in their later years of life.
