0:00:00i
0:00:05and
0:00:13the with come from longitudinal study is a simple of one and three was come
0:00:17from high school graduates from the class of nineteen fifty seven
0:00:20and they've been interview since nineteen fifty seven
0:00:23but they didn't since nineteen fifty seven
0:00:26and the simple has grown over time to include a selected sampling for each relevant
0:00:32graduate i'm and we've also interviewed their stances and have lots of questions about their
0:00:36children and their parents as well
0:00:38so in essence that's over time become of families based
0:00:41sample
0:00:47this string that the study is that it is a longitudinal panel that covered a
0:00:51single cohort over nearly fifty years
0:00:55another important strength is the fact that we have been interfering the siblings of the
0:01:00graduates for innocence over twenty years so we can look at
0:01:05innocents
0:01:06sibling based designs mainly samples
0:01:10the rest that this study so in the early part or in the early years
0:01:13at this study we were focused mostly on educational attainment occupational attainment family
0:01:19as the study of phased
0:01:21the kinds of things that we've asked them are relevant to their a life course
0:01:26perspective so now
0:01:28we're focusing heavily on health
0:01:30psychological well being retirements i'm retirement economic wellbeing
0:01:40well there so there's sort of a range of i think different relevant findings one
0:01:46new area that we've begun to explore it is the interaction between by biological and
0:01:52social factors
0:01:54so well we collect a lot of relevant helped in honour sample and we've also
0:01:58been able to collect
0:02:00genetic data
0:02:01so we can look at how for example gene environments rack to affect people's
0:02:07how to add and especially to affect bins like their psychological well being in
0:02:13we live
0:02:16we've been able to look at
0:02:18how a people's
0:02:22educational experiences including
0:02:26their academic performance is affected health the mortality in my life
0:02:31so there's a lot of work for example looking at the relationship between i q
0:02:34in mortality we measured our respondents like use when they were in high school or
0:02:39they were collected by the state of wisconsin
0:02:41and we were able to demonstrate or keep were able to demonstrate using our data
0:02:47that it wasn't so much i q that how drove mortality it was a much
0:02:53more strongly linked to people's academic performance degrades the rank and high school specifically
0:03:02a couple examples
0:03:04you know more broadly the degree to which we can look at how experiences the
0:03:10cost people's life course in their work family life and their child even
0:03:15how that influences psychological
0:03:18how and economic well being and like life
0:03:21a few but a specific examples would include we have a lot of questions on
0:03:27people's
0:03:28and of life planning
0:03:30and this is of highly relevant policy debate at the moment so
0:03:34how well are people preparing in terms of things like preparing wills
0:03:38or harm healthcare proxies and so is asked a lot of people very specific questions
0:03:43about their planning
0:03:45i'm and then we've been able to look at this is
0:03:47a different heartbreakers still able to look at what protects
0:03:51people to plan
0:03:53four and of life and everything from harm
0:03:56your marital relationships to your educational attainment seem to be relevant in terms of helping
0:04:01us understand who's planning and who isn't
0:04:08well the question i mean are simple is interesting in part because we're on a
0:04:12sort of a cup so the baby hours
0:04:15are simple is just a little bit older
0:04:17i'm but also so we sort of the are simple sort of false and between
0:04:21the baby boomers and the cohort following so that or the or slightly older co
0:04:26for so
0:04:28it's a transition period so for example
0:04:32people older than our call for would have had
0:04:38things like defined benefit plan
0:04:40for the comprise their retirement income a pretty straightforward retirement income stream
0:04:45in our sample you're saying that transition
0:04:49that younger courts or experience for their financial eyes are a lot more complicated their
0:04:54private savings as a lot more relevant to their retirement planning retirement income
0:04:59since things like that
0:05:04one of the greatest ranks at this study is the product of the data that
0:05:08we've collected we've collected information on nearly every aspect of these people's lives so there's
0:05:12always room
0:05:15one it area where there are a lot of work but where we would like
0:05:18to see a lot more is especially related to con cognition so precisely because we
0:05:24have measures of cognition when these individuals were in their childhood and weeping continuing to
0:05:31clark cognitive functioning measures as they age
0:05:33there's a lot of work to be done on helping understand in essence how cognition
0:05:38changes as people a eight
0:05:40what determines those changes how things that happen during your schooling experiences during your work
0:05:46life how whether how factors help shape and genetic factors help change a cognition as
0:05:53people age
