Group think souls don't have any size at all since all individuals are pretending to be intellectual souls on a higher plane of evolving than equally adapting sole positions of ancestry here now, inhabiting space one at a time now.
Projection of what character role playing people say, "we mind our social consensus cradle to grave isn't a person navigating time lived since conception, just people agreeing with denying how evolving happens after birth until dead or extinction happens first. > this isn't a love of life but a regret for ever being born as eternally spearated brain adapting equally alive by heart beats so far.
Brain cannot exceed its own body's time alive now. Reality promises 7 days a week and eternal soul conscience after dead.
