Robert Mugabe (President of Zimbabwe) should watch the above Ducktales cartoon... it teaches a good lesson why you should not keep printing money... The Zimbabwean inflation rate is at world record levels at 231 million percent inflation. Their government budget is sized t $US 3 billion, but in their local Zimbabwean dollars it is 66,500,000,000,000,000,000 - and rising.

Last weeks Battlestar Galactica episode (A Disquiet Follows My Soul) was a little boring compared to the hype of the last episode. That's why I wasn't so keen on posting anything until so late in the week. So much talking so much drama... I know - its necessary for the story but personally I want to see more action! Review(If you don't follow Battlestar Galactica you may like to watch this catch up video). I've avoided the BSG forums this week... I've read Alan's and Mo's blogs though as they are always providing a good read about BSG. All in all it was a decent episode. I liked the camera angles... especially the transition moving from Adama picking up rubbish in the corridor then focusing on Starbuck and Gaeta... All I want is some action! haha

After surveying 800 men, a UK Research team have found that if you were sexually active in your 20s and 30s - especially if you masturbate frequently - you were more likely to develop prostate cancer. However if you were older - in your 40s, then frequent or low levels of sexual activity seems to offer protection from prostate cancer. "Men with prostate cancer were also more likely to masturbate frequently than men in the control group, with the greatest difference in the twenties (34% versus 24%) and thirties (41% versus 31%). The differences were less pronounced in their forties (34% versus 28%) and by the fifties the cancer group was slightly lower (25% versus 26%)." From Science Daily

Other ways to solve the problem:
2x+y = 60 == y = 60 - 2x
x+2y = 75
x+2(60-2x) = 75 == x+120-4x = 75 == -3x = -45 == x = 15
y = 60 - 2(15) == y = 60-30 == y = 30

{15, 30}

Here's a simpler straight forward method of solving the math problem:

2x+y = 60
x+2y = 75
Multiply the 1st equation by 2:
4x+2y=120
Subtract the 2nd to get:
3x=45 ---> x=15

Or if you're an advanced student you can solve this math problem as a set or matrices:
[2 1 60]
[1 2 75] = a

[1 0 15]
[0 1 30] = rref(a)
