The odd part of this news story concerning aging wolves losing their mojo as they age is that scientists assumed this didn’t happen. They figured that wild animals died before they ever slowed down.

That’s bizarre.

Old wolves lose their bite, say researchers who have found that getting old affects wolves’ ability to hunt and moderates their impact on prey.
The discovery helps answer a tantalising question: does getting old impact the athletic abilities of animals just as it does people?
While it might seem obvious that it would, many eminent biologists and researchers have assumed otherwise.
They have argued that most animals tend to die before age wearies them.

Scientists think in “species”. Most of us, including wild animals, live as “individuals”. Of course some live longer than others!
