Point taken!By keeping identities separate, it is less likely data can be aggregated.
Fortunately, if someone does look up my real name including title they quite often end up with somebody in the USA with exactly the same name and qualifications. That adds to the confusion. Who knows what information Google has managed to aggregate on us all? I no longer use Google for searches, but I notice when accessing most webpages that a connection is made to google.somethingorother.
Unfortunately, an increasing number of senior moments does limit my ability to remember too many identities and passwords.
