I should probably read up on the force of gravity on Mars, because gravity is why we make most furniture. We need something to hold us and our stuff off the ground. (OK, a short Google search later, and I found that gravity on Mars is only 38 percent of the gravity on Earth. For comparison’s sake, the Moon’s gravity is 83.3 percent LESS than Earth’s.*) So instead of making furniture to hold us up, we might need to make furniture to hold us down. We might store things on the underside of shelves so they won’t wander off.

All of this leads to one bold but logical conclusion: woodworkers should be the first people on Mars.
* Update: An alert reader (I'm surprised I have any readers, much less alert ones!) schooled me on the gravity percentages above. Turns out the moon's gravity isn't 83% of Earth's but 83% LESS than Earth's. So I took out my Buzz Aldrin sight gag... Got to get your science right.
