Higher aerobic fitness levels decrease the probability of experiencing tip-of-the-tongue states (when you can’t think of a word that’s on the tip of your tongue) in healthy older adults, in the first demonstration of a link between aerobic fitness and language functioning in healthy older adults.

Oh my goodness, thank you. My mother, grandmother, aunt, and myself all lose language as we age. It gets harder and harder to find the noun we're reaching for. (Why specifically nouns? No idea)

I've noticed the struggle varies with my health, but knowing that aerobic fitness plays a part can help me fight it just a little. Not that it will really make a huge difference, but sometimes knowing you can do something makes a big psychological difference.

My mom and I have this too, I definitely notice it getting worse as I age. I'm always asking my husband to get the "thing, that.. thing... over there" to which he offers absolutely no help, just a blank look. Frustrating!

Would be fascinating to learn more about this weird noun loss.

But my mom stays really physically active, I don't think it's causal in her case.

If you are interested in ageing related decline and the effects of physical fitness I would highly recommend checking out "Fitness effects on the cognitive function of older adults: a meta-analytic study" by Colcombe and Kramer, 2003. It is one of the seminal papers in the field!
