This post doesn't have much to do with manufacturing or design but it's a funny story. At least I think so.... :)
I took a little break and went to Las Vegas for 4 days. I didn't gamble, but had a great time anyways, I strongly recommend this trip for everybody.
One afternoon I decided to go and see the Grand Canyon but all the tours were 8-10 hours long and I didn't want to spend my valuable time on a bus. I decided to go on a helicopter ride which was an hour and a half long. Before we were getting on the helicopter they asked me about my weight. Without thinking for a second:

- 76.4 kg or 168.4 lbs.

The guy started laughing, and that made me realize how much testing was involved in creating these scales. Today for example I measured myself about 10-15 times....

I know this picture doesn't look real but I took it myself from the helicopter.
