Take a look at this site, called ‘Gapminder’.
It is a fascinating piece of software that displays the positions of countries on a graph of different factors set against each other.
If you look at the default graph on this site, you will see that the most prosperous and longest living people live in Hong Kong.

Speaking of useful tools, check out this one, called ‘Sitefinder’: The Mobile Phone Base Station Database. You put your postcode into the slot, and it returns a map of all of the cellular telephone masts in your immediate area. Clicking on the blue triangles brings up information on who operates the transmitters and the amount of power they are outputting.
This is an amazing resource for those who do not want to buy a house that is being drenched in emissions from the many towers that provide near blanket coverage of the UK.
