Cathi Morgan's Twin

<p>&nbsp;

I was alerted to the possibility that research on twins could have been key, when I remembered the unusually high number of twins at the Catholic (Jesuit) school we attended. &nbsp;Many had recently moved to the area, like ourselves. &nbsp;Many moved back up to the north of England as we did, in 1969. &nbsp;I have since discovered a specific area of research that involves both MZ (identical) and DZ (non-identical) twins who have similar significant life events.</p>
