To calculate someone's age, we subtract their birth data from the current
date. We have to give the current date to SPSS using the date.dmy function.
Use compute to calculate age as being equal to d.o.b - date.dmy(23, 2, 99)
[or whatever is today's date].
However, this will give age in seconds (because of the way that SPSS stores
time. To calculate age, we must calculate age_in_years = age-in_seconds /
(60 * 60 * 24 * 365.25).
