Yup, the 2x2 can hold 950lbs: https://news.ycombinator.com/item?id=4870283

We can also observe this (to a lesser degree) when they build two story Lego statues like at the Mall of America.

I'll admit I've never seen a huge Duplo statue, but I assume the load limits are similar.

Strength I don't know. Pointiness does for sure.

Perhaps. Plastic structural rigidity varies with twmperature. Temperatures fluctuate throughout the day. This natural variation is probably insignificant in most cases though.

If we're getting technical, the weight of a human does vary throughout the day. Generally, while asleep, your mass decreases. You're always gradually losing mass as you inhale O2 and exhale CO2. You're also losing mass as you exhale moisture, and you may also sweat.

Thus an adult human male (who sleeps, say, 10pm to 6am) is less likely to break a lego brick at 2am than at midnight and more likely than at 4am.

It was a joke about stepping on one of my kids' legos in the middle of the night while half asleep.
