 Yeah, tui cu~ng tha^'y ma^'y ca'i stat na`y.  Cu~ng nhu+
pha^`n ddo^ng stat ve^` longevity, ma^'y ca'i na`y cu~ng kho' tin.
Ne^'u la` ngu+o+`i o+? ddo^`ng ba(`ng, co' nhie^`u cu+ da^n thi`
ddo^. tin ca^.y kha' ho+n.

 No'i chung life expectancy cu?a VN thuo^.c va`o ha.ng "Not
to bad", nhu+ng co`n long way dde^? catch up vo+'i ca'c nu+o+'c
tie^n tie^'n.  O+? VN nga`y nay, life expectancy va`o khoa?ng
63 cho nam va` 68 cho nu+~a, tu+o+ng ddu+o+ng vo+'i ca'c nu+o+'c
trong vu`ng DNA (va` cao ho+n Nga).  Nhu+ng so vo+'i ca'c nu+o+'c
Ta^y phu+o+ng (72 cho nam va` 79 cho nu+~) thi` VN co`n pha?i
do a lot of public health things.

 Life expectancy ta(ng trong tho+`i gian ga^`n dda^y chu?
ye^'u la` do ty? le^. tu+? vong trong tre? em ddu+o+.c gia?m.
Nhu+ng cu`ng lu'c, ty? le^. abortion (tu+'c la` pre-natal
mortality) cu~ng ta(ng.  Nhu+ va^.y no' cu~ng cancel out.  Co'
tay demographer no. dda~ ti'nh la` tuo^?i tho. chi'nh xa'c nga`y
nay chi? khoa?ng 40!

 Tui co' ca?m gia'c la` mi`nh dda~ dde^'n ca'i upper limit
cu?a life expectancy.  Ngay ca? chu'a co`n co' no'i "Seventy years
is all we have - eighty years, if we are strong; yet all they bring
us is trouble and sorrow; life is soon over, and we are gone."
(Psalm 90:10).

 Sa(~n no'i chuye^.n longevity, tui nho+' ca'ch dda^y la^u
ro^`i, tui co' ddo.c mo^.t hypothesis ra^'t ta'o ba.o, dde^` nghi.
kho^ng ti'nh lifespan ba(`ng na(m tha'ng, ma` ba(`ng nhi.p tim.
Tay biologist Vasilios Valaoras la`m nhie^`u thi' nghie^.m va` theo

khoa?ng 1 ty? la^`n la` che^'t.

 Nhu+ng ta.i sao co' ddo^.ng va^.t so^'ng chi? va`i na(m,
va` co' loa.i la.i so^'ng ca? va`i chu.c na(m?  Tra? lo+`i: Ca'i

 The^' co`n loa`i ngu+o+`i thi` sao?  Nga`y xu+?a nga`y xu+a,

 Co`n con ngu+o+`i nga`y nay?  I leave it to you to sort it out!
