The World Needs EXtroverts and Introverts
The world is full of extroverts and introverts. Society needs them. Some must lead and others must follow. This is the normal way of things. Can you imagine if everyone was an extrovert. There would be arguments aplenty. Nothing would be settled.
Extroverts need people. While their behavior will to a degree drive others away, extroverts don't like to be alone. Introverts on the other hand like their own company. They can happily work on their own for months.
The problem is that these categories are not clear cut. There are some in the middle, those who have characteristics of both groups. The way people behave in their spare time is the best indicator of where they fit. Introverts avoid parties because it is a drain on them. They prefer to go fishing, for example. Extroverts go up the pub to mix with others.
Both groups will eventually have to change as their needs are fulfilled. Body and mind tells them to switch off and go the other way. It may be only for a short time, but batteries can be recharged and they can again push full speed ahead to where they are most comfortable.

Australian and Mediterranean Great White Shark Evolution
Luck plays a large part in evolution. Climate suddenly changes and if by chance a species of animal carries suitable genes to flourish in the new environment that animal lives on. Other species die off because they cannot cope.
New findings about the great white shark highlights this. Australian great whites and the Mediterranean type have genes that point to common ancestry. It is believed that a few related female sharks split up. Some going north to the Mediterranean from the larger gene pool in the south, or they peeled off from the main group in the Atlantic some going north the others going south. Narrow channels in the Mediterranean stopped this group from rejoining the Australian gene pool.
This happened 450,000 years ago. Mutations since that time make the timeline clear. It is believed that swordfish and tuna the main food of the great white also split off from the their main groups. Great white sharks followed the food supply.

Who Is Spoilt Mr Forrest?
Andrew Forrest chairman of Fortescue Metals Group has been a critic of the mining tax. This appears to be for mainly selfish reasons though he does claim that the tax will reduce investment in the mining sector. He does not come across as a caring person and worrying about the future economic welfare of other Australians seems to be far from his thoughts.
It is odd that when people criticize others the name calling seems to apply more appropriately to the caller than the target. When he calls environmentalists "spoilt children" a good look at him shows he is the spoilt one. As well as mining he is a farmer, so he often faces harassment from greenies.
Being a free society Mr Forrest has a right to say this, or say anything else that intends to bring all environmentalists down. However, a cursory glance at Andrew Forrest makes one feel that there isn't much in his almost empty head apart from a dollar sign.
