averages are statistical things and who knows what they include
  that might not be applicable to you - or don't include. You can
  even pick your own age that you want. Think about it: None of us
  knows anyway. Doctors predictions are often just as wrong as an
  Astrologer. Of course Doctors have better statistical info at
  hand but consider: you're not a statistic. I pick my estimate
  between 84-88 yrs. Could be tonight. I don't expect longer but
  it could be longer as well. Might be less. I dunno. 'Til then, I
  got at least this 16071st day. If I get up tomorrow, I have this
  16072nd day. It's a marvel to be honest smile emoticon
