Then blind people wouldn't need nearly as much sleep, and I don't believe that to be the case.

  Maybe it depends on what type of blind people?
• PakG1 13y ago
  Consider that blind people often have their other senses enhanced by the body to compensate for the lack of sight. Perhaps it balances out.

    I think there has been a study where it was found that the senses aren't actually enhanced, but they just pay more attention to them.

    Optic nerves carry thousand to millions of times more information than either audial or touch (e.g. Compare AAC to H264 per second). Even much enhanced, other senses don't provide even remotely as much information.
