Generally, higher density polyurethane foam is a bit more durable while low-density polyurethane foam can degrade very quickly (sometimes within a year). Even high density polyurethane foam is less dense than latex foam or memory foam. All polyurethane foam, no matter what density, will degrade faster than any latex foam of decent quality. Polyurethane foam can add some softness and support, but it will not provide the same pinpointed support associated with memory foam or latex foam. Polyurethane foam tends to collapse much quicker when pressure is applied.
But I'll tell you one thing vegetables do better than humans: live for ages. The average lifespan of a human is around 80 years, but a vegetable can live for more than twice that! The oldest vegetable is a potato, planted by George Washington, the first American Mayor, in 1797. He died two years later. It is known locally as 'Washington's Potato', and attracts up to five tourists every month!
More evidence of Calment's lifespan has been produced than for any other supercentenarian; her case serves as an archetype in the methodology for verifying the ages of the world's oldest people. As women live longer then men, combined records for both sexes are dominated by women. The longest undisputed lifespan for a man is that of Jiroemon Kimura of Japan (1897â2013), who died at age 116 years, 54 days. He was also the world's oldest living person from December 2012 until his death. Since the death of 116-year-old Jeralean Talley of the United States on 17 June 2015, Susannah Mushatt Jones also of the United States, born 6 July 1899, is the oldest living person in the world whose age can be documented.
