“In a series of studies over the past 15 years, Villeda and others at a few like-minded labs in places like Stanford and Harvard have shown that when infused with blood from young mice, old people heal faster, move faster, think better, remember more.The experiments reverse almost every indicator of aging the teams have probed so far: they correct signs of heart failure, improve bone healing, regrow pancreatic cells and speed up repair of the spinal cord. “It sounds sensational, almost like pseudoscience,” says Villeda. It’s one of the most provocative research on aging in decades.

“For all of this to happen, the team had to clear the vegetation in the middle of the road and cut the bushes, but also being careful not to disturb how nature had already reclaimed the base. Giant, open manholes everywhere – “big enough to gleefully swallow a Bentley wheel,” Sayer added – had to be closed and secured. They built small concrete ramps to connect all the different sections of the course.

“There are over 144,000 cemeteries and cemeteries in the United States, according to a NASA cartographer; they cover over 4,300 acres in New York City alone. With all this terrain, there’s plenty of room to test lawn care techniques that break with the century-and-a-half tradition of over-pruning, over-watering, and over-fertilizing open spaces. A strategic, but laissez-faire approach, as more and more research is finding, can save resources and help mitigate human impacts on local wildlife and climate change. “
