Take a Walk
You don’t literally need to stretch your legs to clear your head and refresh your spirit—you can do it in your mind’s eye.
For those times when you feel you’ve reached the end of your tether, snap on the (virtually) real thing at discovery.com and take a sedate excursion in zero gravity to repair the International Space Station. The interactive stroll is based on an actual mission in 2000.
Wander Philadelphia on a self-guided ramble at theconstitutional.com and stop by the Betsey Ross House, Independence Hall and the Christ Church Burial Ground, as well as lesser-known venues such as the B. Free Franklin Post Office. It’s the only active postal center in the U.S. that doesn’t fly an American flag, because a national banner didn’t exist when Ben Franklin became the first postmaster general in 1775.
