I am afraid this is wrong.  We have measured/traced a number of well-known
C programs, and found that for some the above assumption is true, but for
others the reverse is, i.e. old objects tend to point to younger ones.

I don't have the report in front of me.  I'll check tomorrow exactly which
programs exhibit this behaviour.
