Aging is characterized by a decline in resilience, leading to an inability to compensate for damage and recover from events like illness or injury.

“I think that the um um what's happening is this damage is impacting this network that's keeping you healthy, this homeostatic network. And it's in little ways here and there and here and there. and the network compensates for that and does okay. But when enough damage happens, you just can't compensate anymore for events that are happening. So when you get sick, you get some, you know, viral infection or you fall down when you're 80 and break your hip, you just don't have that homeostasis pathways in place to allow you to recover and compensate for that.”
