Lego
The acrylonitrile butadiene styrene polymer from which Lego bricks are constructed demonstrates remarkable resistance to degradation. Laboratory testing confirms these bricks maintain structural integrity for 300 to 1,300 years in marine environments. The interlocking mechanism remains functional after thousands of connection cycles, with clutch power diminishing by less than five percent over decades of regular use. Archaeological evidence suggests Lego bricks will outlast the civilisation that created them.
Panda
The giant panda exhibits limited durability by biological standards. With a maximum lifespan of thirty years in captivity and considerably less in the wild, the species struggles against its own evolutionary choices. Their digestive system, designed for carnivorous intake, processes bamboo with merely seventeen percent efficiency. The species narrowly avoided extinction in the twentieth century, requiring substantial human intervention to maintain population viability.
