Carrying luggage around

There's a certain piece of luggage that I normally use on business trips. It has wheels and an extendable handle, allowing the weary traveler to simply wheel this thing around.

Guess what? I almost never use that feature.

I'd rather carry the bag around. First, this helps build up my shoulder and forearm muscles, and it helps burn calories. This is really helpful when you've spent most of the day sitting in an airplane with no place to go.

And second, I can get around much more quickly when I carry this bag around rather than dragging it behind me. Ditto for my heavy laptop bag.

One of my co-workers -- a fairly tall fella -- said that he needs a small laptop. "I don't want to get tired from carrying my laptop around," he said. "That's why I need one that's very small and very light." I won't begrudge him that, but since you pay a price premium for small laptops, I'd rather own a larger one and then build up the strength needed to carry it around. Heck, my laptop is very heavy, and I carry a massive amount of other stuff in the same bag. Do I travel a lot? Not really, but I do have to carry this bag to work everyday. I honestly don't mind.
