Lost wallet returned 39 years on
A US man has praised the "good, honest" people of Utah after a wallet he left behind 39 years ago was returned to him in Pennsylvania. Doug Schmitt, 57, left his wallet on the counter of a petrol station in Logan, Utah, in the spring of 1967.
The owner put the wallet in a drawer in the hope Mr Schmitt would come back to collect it.
Decades on, his son-in-law found it, tracked Mr Schmitt down on the internet and sent it to him.
Full head of hair
The wallet still contained $5 in cash and 8-cent airmail stamps. An equivalent stamp today costs 39 cents.
It held Mr Schmitt's student identity card from Utah State University.
"I had a real full head of hair back then," said Mr Schmitt.
He also found pictures of his high-school girlfriends and a dry-cleaning ticket in there.
"It makes me wonder if I still got some dry-cleaning out there," he said. "I don't know."
Ted Nyman was clearing out his father-in-law's estate when he came across the wallet and sent it 2,158 miles (3,472 km) across the US.
Wonderful
Mr Schmitt, an antiques dealer, said he was used to looking through people's old relics and letters, but was surprised to find himself looking at his own history.
"I never thought I would be the object of something like this - not at this age, anyway," he said.
"It's wonderful that people will take the time to research that, then return something to someone they don't even know," his wife, Vickie, added.
"It's great to see how he looked when he was a freshman in college."

Skydivers claim new world record
An international team of skydivers says it has set a new world record for the largest connected free-fall formation. World Team 2006 said all of its 400 jumpers, from 31 countries, had held hands for several seconds during a jump in north-eastern Thailand.
It said the record had been certified by judges from the Switzerland-based Federation Aeronautique Internationale.
The previous record of a 357-member formation was also set by World Team skydivers - in 2004.
Earlier failures
"What an amazing jump it was, 400 people in one formation! It was beautiful!" World Team 2006 organiser and record jump participant BJ Worth said.
"When we landed we all felt that everything had come together and we had the record. The team has been working hard to make this happen," Mr Worth said.
The divers managed to clinch hands in the skies over Udon Thani, drifting down in a circular formation for nearly five seconds, the team said.
They then broke off at 7,500 feet (2,286m) and flew away so that they could safely deploy their parachutes.
The group had failed to completely link up for a measurable amount of time in two earlier jumps on Wednesday.
World Team 2006 is an informal association that includes current and former world champion skydivers.
The record jump was part of festivities honouring the 60th anniversary of the reign of Thailand's King Bhumibol Adulyadej.

NZ diver survives 72 hours adrift
A New Zealand diver was found alive on Wednesday after three days adrift in waters near the capital Wellington. Robert Hewitt, 38, was reported missing on Sunday after failing to surface from a dive near Mana Island, off the west coast of the North Island.
The former navy diver's colleagues found him after three days without water and only a crayfish and four sea urchins from his dive bag to eat.
"I don't think I would have made last night," Mr Hewitt told local radio.
Dehydrated and cold
Mr Hewitt, the brother of former All Blacks rugby player Norm Hewitt, said he had been suffering hallucinations after so long without fresh water.
"I honestly thought yesterday [Wednesday] afternoon I was at home. I started taking off some of my gear, here and there, floundering around like I was lost," he told radio station Newstalk ZB.
Mr Hewitt was said to be dehydrated and very cold after three days in the water.
A police launch brought him to shore, where he was met by weeping relatives before being taken to Wellington Hospital.
From his hospital bed he said: "The love of my fiancée and family got me through, and the knowledge that I have gained from the navy allowed me to adapt to the different conditions."
He said his hopes of being rescued faded after he surfaced and realised he was being swept north along the coast.
"Just one crayfish and four kina [sea urchins], after the first night I knew I had enough sustenance for 24 hours," he said.
"I must say I was dying of thirst, but you look at the young kids overseas who haven't got water to drink so I just put myself in a mental state like that," he added.
He joked: "I shed a few kilos, but maybe they were the kilos that needed to be shed."
Lieutenant Commander David Turner, of the Royal New Zealand Navy diving team, said chief petty officers Lyle Cairns and Buzz Tomoana decided to check local information about a sheltered cove where seaweed and flotsam usually washed up.
"They went to see if there was anything there that could give searchers a clue - and it was there they found him," he said.
Mr Hewitt's brother Norm said the extended family - who are part indigenous Maori - met at the local marae, or meeting place, to pray for his safe return on Monday.

Self-cleaning bathroom on the way
Nanotechnology may yet rescue us from the drudgery of the weekly ritual of blitzing the bathroom. Scientists in Australia have developed an environmentally friendly coating containing special nanoparticles that could do the job of cleaning and disinfecting for us.
"If you have self-cleaning materials, you can do the job properly without having to use disinfectants and other chemicals," says researcher Rose Awal at the Particles and Catalysts Research Group, University of New South Wales, where the coating is being developed.
Previously self-cleaning materials were limited to outdoor applications because ultraviolet light was required to activate the molecules in the coatings.
These surfaces contain tiny particles of titanium dioxide, which become excited when they absorb ultraviolet light with a wavelength of less than 380 nanometres.
Light activated
This gives the particles an oxidizing ability stronger than chlorine bleach. The excited particles can break down organic compounds and kill bacteria.
The new coating contains modified particles of titanium dioxide, which are doped with other cations like iron or vanadium and anions like oxygen, nitrogen or carbon.
This coating can absorb light at the higher wavelengths in visible light, such as the bathroom light.
Lab experiments revealed the surface of coated glass could kill the bacteria E. coli (Escherichia coli) and degrade volatile organic compounds in visible light.
The oxidising properties also mean fungus cannot grow on the surface. And because the coating is hydrophobic - it does not like water - the water simply slides away carrying any dirt with it, rather than gathering as droplets.
Using the coating in baths and sinks would not pose any problems with skin irritation, according to Amal.
"When the bath is filled, the water would attenuate the light so I don't think the surface would activate. It will only be active if the light can reach the surface," she says.
Possible disadvantages
Friends of the Earth spokesperson Mary Taylor said that if materials like this could prolong the lifetime of an object, this would be an advantage in environmental terms.
But she warned: "Such a hi-tech material might have some disadvantages.
"We would have to consider, for example, whether the material could be recycled or disposed of safely, and how much more energy went into production of the raw materials and its manufacture."
However, she added: "Less time cleaning the bathroom is rather appealing, and there might be some special uses, maybe in hospitals, where such materials could be a boon."
