 Being present, yeah. Sleep disturbance, yeah, of course. If you're at risk for cognitive decline, particularly in old age, if you have so much as any kind of infection, it goes systemic and it affects the brain. So the brain doesn't sit in isolation. And my mom, when she was well slept and particularly when she was exercising, she definitely did have more of a spring in her step and cognitively was a bit more lucid.
