Bury jewelry shop worker to take on Tough Mudder
5:00pm Friday 27th September 2013 in News By Andrew Bardsley, Reporter
A WORKER at a Bury jewellers is hoping to be a shining star when he competes in a stamina-sapping event to raise money for a cancer charity.
Ryan Unsworth, who works at Peter Jackson in The Rock, is preparing for the Tough Mudder challenge to be held at Cholmondeley Estate in Cheshire on October 5. He is part of a team from stores across the North West, who are raising funds for the Roy Castle Lung Cancer Foundation.
The Tough Mudder event will test the group to the limits, as it comprises of a 10-12 mile obstacle course designed to test strength, stamina and determination.
Mr Unsworth, aged 24, of Walmersley Road, says the charity is close to his heart. His best friend was diagnosed with the disease at the age of 16 after suffering from water in the lungs, and now aged 23 has been given the all-clear after receiving treatment at The Christie.
He said: "I did a Race For Life a few years back but this is a bit scary. I have been training and I feel ready but nervous."
The charity was founded as the Lung Cancer Fund in 1990 to raise awareness of the disease, and in 1994 was renamed in honour of entertainer Roy Castle, who died in September, 1994.
The star of TV show Record Breakers spent much of the last year of his life working on an appeal to raise money for a £12 million international centre for lung cancer research in Liverpool, which was opened in 1998.
The team aim to raise £2,000. To make a donation: visit justgiving.com/PeterJackson Jeweller

The White House on Health Insurance Reform
TPM writes Major White House Players To Run Point On Senate Health Care Bill. "White House Chief of Staff Rahm Emanuel and Nancy Ann DeParle, Obama's chief health care adviser, are expected to be at the table throughout the talks. White House Office of Management and Budget Director Peter Orszag also is set to play a role, primarily on issues where health care and the federal budget intersect."
Now if they could just figure out how to combat micro-ideas.

Obama is turning into my worst nightmare......Jimmy Carter.
He stands for nothing. Sure he talks a good talk, but then...nothing.
The day he took office, he should have ordered the Justice Department to begin immediate investigations into illegal financial activities related to the economic meltdown and to torture carried out by US personnel.
Then he should have laid out a simple health reform agenda with no more that 5 or 6 goals and told the Democratic Congress to go make it happen....and then hold them to it, instead of letting it turn into a circus and freak show.
Then he should have made closing Guantanimo Bay by year's end a done deal. What, we can't give halliburton a billion dollars to reopen alcatraz, and make it so that the showers electrocute the prisoners.
Next he should be rapidly withdrawing troops from Iraq and finalizing a new political strategy for Afghanistan, cause their ain't no military solution to be had there.
If he had done these things, he would have the vast majority of the public behind him, but he has dithered.
Unfortunately, he has proven himself to be an empty suit.....all talk and no action.
So far to me, he looks like a peanut farmer.
It's no wonder the repubs can call him a liar during a speech to a Joint Session of Congress, and get rewarded for it.
While, as far as I know, he's not quite a liar....there is little evidence to show that he means what he says.

How Can Evolutionary Biology Explain Why We Get Cancer?
Over 500 billion cells in our bodies will be replaced daily, yet natural selection has enabled us to develop defenses against the cellular mutations which could cause cancer. It is this relationship between evolution and the body's fight against cancer which is explored in a new special issue of the Open Access journal Evolutionary Applications.
Hormone-Mimicking Chemicals Cause Inter-Species Mating
Hormone-mimicking chemicals released into rivers have been found to impact the mating choices of fish, a new study has revealed. The controversial chemical BPA, which emits oestrogen-like properties, was found to alter an individual's appearance and behavior, leading to inter-species breeding. The study, published in Evolutionary Applications, reveals the threat to biodiversity when the boundaries between species are blurred.
