SPF?

Recently I've been wondering what exactly SPF means and found this simplified answer on http://www.wiki.answers.com/:

SPF stands for sun protection factor. Higher SPF numbers would allow a person to be in the sun longer without burning. SPF 30 means that your skin will not burn until it has been exposed to 30 times the amount of solar energy that would normally cause it to burn. In other words, if you start to burn at 10 mins, applying an SPF 30 would know take 300 mins. to start burning (30x10= 300). However, there are many limitations to this rating (time of day, skin type, uv index, sunblock brand, water, sweat etc...) Also, SPF is just the protection factor against sunburn or UV B radiation and does not have any relation to UV A radiation, which causes long term skin damage.

The Future of Food

If you are interested in learning more about the nature of genetically modified food - a prevalent phenomenon in America that most people know little about - I recommend the documentary "The Future of Food". At this point companies are not required to label GM foods - even though the safety of GM foods is still inconclusive and appears to be a large scale experiment on the part of biotech companies. This eye-opening documentary will also discuss the unethical practices of farming monopolies such as Monsanto (heart-breaking stories from farmers) and the controversy surrounding patenting nature (absurd, I know).

After watching the documentary I am more energized to shop at farmer's markets and buy as much organic produce (as well as meat and dairy) as possible. In the film you will witness the alarming health hazards GM foods have posed on animals used for experiments. Imagine, this is the same stuff we eat every day. No wonder we are such a sick nation!
