High-altitude headache

Q I was visiting my son in Boulder, Colo., recently and came down with a nasty headache when we went hiking in the mountains outside of town. I was shocked because Boulder's elevation isn't that terribly high. Could I have had altitude sickness, and can I avoid it next time?

A Altitude sickness usually doesn't occur until you're at 7,500 feet or so; Boulder nestles in the mountains at a mere 5,400 feet. Whether altitude caused the headache depends on how high you climbed and how quickly after your arrival you headed for the hills.

Above 7,500 feet, the lesser amount of oxygen in the air means our red blood cells have less oxygen to deliver to our vital organs, promoting headaches in milder cases (known as acute mountain sickness) and a host of life-threatening problems in the worst cases. Our bodies compensate by producing more red blood cells, but that takes time. Next time you're in Boulder, hold off on the hike until you've been there a few days so your body can acclimate, and be sure to stay well hydrated by avoiding alcohol and drinking plenty of water.



Delta starts bag-tracking

Delta Air Lines can't promise not to lose your bags, but it has launched an online service to let you track the movement of your bags at each stage of their journey from baggage check-in to airport arrival. You can even go online during your flight to see whether your bag made it onto your plane. Delta says it is the first U.S. airline to provide an online service to follow the movement of luggage before it is lost. This is how it works: Baggage handlers attach a tag with a bar code to each piece of luggage. As the luggage is screened, sorted and loaded into planes, workers scan the code at several points in the process. Passengers who go to www.delta.com/baggage/BaggageTrackStatus.action can type in the numbers on their luggage tags and see when and where their bags were last scanned. A Delta spokesman said the airline is working on an application for smartphones and other mobile devices.



Rembrandts headed to U.S.

For the first time since Rembrandt's death in 1669, the Louvre in Paris has brought together the seven portraits of Jesus attributed to him. (Only two are signed, which could mean that some are studio works.) "Rembrandt and the Face of Christ" travels to the United States for display at the Philadelphia Museum of Art (Aug. 3-Oct. 30) and the Detroit Institute of Arts (Nov. 20-Feb. 12, 2012).

Rooms for 5 - or more

The website Room for 5 (www. roomfor5.co.uk) lists hotels that can accommodate families of five (or more) in one room or connecting rooms. It was founded by Drina Murphy, a British mom of three, and features more than 5,500 properties in the United States and Europe. But searching for a single city is not easy. You must pick the country, then the state or county, and then scroll through an alphabetical list of cities.
