There are people who worry that as they age, they'll no longer be up to doing all the things physically that they used to do. Case in point: Laszlo Aranyi. A Hungarian national, he has long prided himself on being as strong as a horse . But, as he put it not long ago, with the 60th anniversary of his birth just around the corner, "I wanted to prove that I was still fit." So, to test himself, he decided to set out on a journey across his country - on foot. It took him 22 days to cover the 430 miles from Zahony in the east on the border with Ukraine to Szombathely, on the boundary with Austria - nearly the widest possible axis. That's an average of 19.5 miles a day. Not bad , huh? No, especially when you consider that Aranyi did it pulling a carriage, as if he were, in fact, a horse. And what's even more impressive, the carriage weighed 924 pounds. Just to ensure that all went well, he had a friend follow him on a bicycle. But as it turned out, the trip came off without - you should pardon the expression - a hitch . Said Aranyi afterward, "The only hard part was getting up the hills and then balancing the carriage on the way down."
