Heritability of lifespan, GG91, notes

GG91, p33, cite Jacquard, 1982. Heritability coefficient for human lifespan is 0.16.  GG91 interpret this as: Even if the lifespan of both parents exceed the mean lifespan by 20 years, their offspring will gain on average only 0.16x20=3.2 extra years from their genetic 'inheritance'.

Page 34. GG91 then argued that "selection for an increase in life span is ineffective". GG91 then used the heterozygote Aa example to make their point.

page 35,
GG91 cited that heteozygotes often live longer than homozygotes. Bileva et al 1978, 1981, Nekrasov 1981, Shakhbazov 1980.
