Parental age at death and age at first birth

Interesting study published in Experimental Gerontology which examines the age of death for parents and the age they had their first offspring.  

The abstract:

People age at different rates and the available evidence suggests that the rate of aging is partly inherited from previous generations. This heterogeneity in aging is evident already in midlife, but to what extent aging is associated with the timing of events earlier in life is not fully known. Here we aim to shed light on this topic by investigating the trade-off between reproduction and aging postulated by evolutionary theories of aging.
