Gerard, From all the messages, it seems to me we can define 3 kind of values :
1) Values with a genuine relationship with date of birth : youth, middle age, elderly... Those who can manage fuzzy sets will do it that way, while others will have to use simple time intervals based on date of birth. Can we define these fuzzy sets or intervals as standards ? Maybe we should work on it. 2) Values somewhat related to age, but with a non linear/standard relationship : date of conception, date of first flue, date of first walk... These dates should be recorded somewhere, as unrelated informations. 3) Values whose name includes the term "age", but are, in fact, ratios : mental age, growth age... These informations are neither dates, nor time intervals, but only some comparisons versus a "standard developpement" ; from my point of view, they are some kind of ratios and have little to do with this discussion.
