Key points from article :
Pheidole dentata don’t show any signs of aging.
Their brains appear just as sharp and they are just as active.
Worker ants typically live for around 140 days.
May suffer a steep decline just before dying.
So not immortal but most people would like a healthspan that is very close to their lifespan like these ants.
The study was published in the Proceedings of the Royal Society B journal.
