it doesn't feel like life expectancy changes would make such an impact, since it 'feels' like many of the celebrities died before life expectancy. i say feels because I haven't seen an age breakdown. would it make sense to make many random draws of non-celebrities who died and compared the age of that group against the celebrity group?
