Unfortunately, it took 4 years to come up with an acceptable technique, another 4 years to finally figure out an optimal way to apply it, and two additional years to generate and correctly inter- pret key data on the division cycle.

Of course there were personal milestones along the way, including the births of sons Charlie and Michael, but without sheer stubbornness in the face of endless setbacks, my research career would have collapsed on more than one occasion.
