What happens inside the head of a soccer player who repeatedly heads a soccer ball That question motivated a study of the brains of experienced players．
Researchers at the Albert Einstein College of Medicine in New York selected 34 adults ， men and women． All of the volunteers had played soccer since childhood and now competed year﹣round in adult soccer leagues． Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year ， as well as whether they had experienced any known concussions in the past．
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned， using a complex new M．R．I． technique which can find structural changes in the brain that can 't be seen during most scans．
According to the data they presented ， the researchers found that the players who had headed the ball more than about 1 ， 100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory ， attention and the processing of visual information ， compared with players who had headed the ball less．
This pattern of white matter loss is " similar to those seen in traumatic brain injury" ，like that after a serious concussion， the researchers reported ，even though only one of these players was reported to have ever experienced a concussion．
The players who had headed the ball about 1 ， 100 times or more in the past year were also generally worse at remembering lists of words read to them ， forgetting the words far more often than players who had headed the ball less．

From American Express， wedding guests will，on average，spend ﹩673 on each wedding they attend this year． It includes airfare （﹩225）， hotel （﹩170）， dining out （﹩116）and dressing up （﹩95）and the gift． If you have weddings to attend this year， here are some tips for you to avoid breaking the bank．
1． Book flights in advance
The moment you decide to attend a wedding is the time to check flight prices at the best time． Plane fares are higher in the summer， especially in July and August． Booking in advance will save you money， as will watch for sales on lower﹣cost carriers like JetBlue and Frontier． You can check Google Flights for a calendar of prices showing the cheapest days to fly from apps like Hopper to get real﹣time alerts when a fare is at its lowest price point．
2． Don't blow your budget on the gift
If you've got the money， an expensive gift is lovely． But there's no need to take out loans to prove your love for the happy couple． Skip an expensive necklace by giving （an appropriate amount of） cash instead． To save on the gift， consider making one： A photo album or scrapbook of memories with the bride and groom shows how much you care． You could also share the gift with other guest（s） or even make gifts with DIY ideas by yourself to save money．
3． Use old dresses and suits
You don't always have to be on a new dress for a wedding． While men have the option of repeating their suits， women are more likely to spend money on new clothes for the special occasion． But before you take out your wallet， consider reinventing something already in your closet． Belts， colorful scarves， shoes can bring life to any outfit．
