First what matters is the sum of all deaths by a specific age not deaths at a specific age.
Anyway, the average age of fathers in the US is 31. Men over the age of 40 make up 9% of all fathers. So, dying at 30 or even 40 is directly meaningful from an evolutionary standpoint. Further, losing parents is a significant issue.
