Seems to work well enough for the elephants, though, and new evidence has shown that up until only a few thousands of years ago, there were still mammoths alive in certain parts of the world. Size-wise, an average mammoth relates to an African elephant as an Indian elephant relates to a horse. And mind you, elephants are among the most intelligent animals on the planet. They're right up there with dolphins and whales.
Physicists are not biologists. And whether Earth's gravity has ever been less than the 9.82 m/sec² acceleration at sea level which we currently experience or not, I would also like to point out that the brachyosaurus stood at a length of 30 meters. And like most quadruped dinosaurs, they actually had two brains: one in their skull and one in their lower back, at about the location of the pelvis. The latter brain was for most part dedicated to operating the hind legs, the tail, and part of the digestive system.
As for bipeds, the tyrannosaurus rex stood at approximately 4 meters (~13 feet) at the hips — standing fully erect, it would have been twice that high — and it was by far not the biggest bipedal carnivore to ever roam the Earth, even though it was long believed to have been. Recent fossil discoveries indicate that the T-Rex had a couple of cousins (across different eras) of much greater size.
Capital punishment is at the very least just as bad as the crime it is supposed to be a punishment for, because it is the execution of an unarmed and already detained person who can no longer harm society at that point in time. By consequence, it is nothing short of premeditated murder, in a similar vein to how taxes are legalized theft and fiat money is legalized extorsion.
In addition to that, the proponents of capital punishment claim that it serves as a crime deterrent. Well, in that case, it doesn't seem very effective, or does it? A psychopath will never assume responsibility over his own actions and also always refuses to acknowledge the consequences, plus that they usually also think that they're smart enough to get away with whatever they're doing. So the mere fact that any particular crime would be punishable by death is never going to stop a psychopath from committing such crime. Just look at the gang rape cases — several of which were so violent that they have also directly led to the death of the victims within hours after the rape — in India and South Africa. I don't know whether South Africa still supports capital punishment, but I know that India certainly does. And India also has the highest rate of gang rapes — many with a fatal ending for the victim (and any male in her company) — in the world today.
And on top of that, public executions as they still exist in China and Saudi Arabia today, and as they still used to exist in France up until 1939 — France would still carry out the death penalty until 1977, but no longer in public — are essentially legalized terrorism, which, ironically, traumatizes the innocent far more than that it would discourage the criminals and psychopaths.
I second that. Barry's the real deal, and unlike most of these celebrities in the alternative community, he's no showboat and he doesn't have a narcissistic agenda.
