Surely it's as pointless to record an age as a property, as it is to 
stop a clock at the current time, and say "there, that's nailed it".  
Current age is the distance between two points in time, one fixed and 
one not (unless you're talking about "age of a person when some other 
event, such as their death, occurred").
