Obviously there is some training here and kudos to the lady, but no doubt her genetical baggage is giving her some advantage here. She's got older not because she's training, she's able to train and perform at this level in spite of being older.

It's entirely possible training has extended her life already.

Boring example but an obese woman with type II diabetes her age might already have had one life-threatening fall, may already have other severe health challenges.

Whereas a woman her age with such good vascular health could be delaying the onset of significant vascular dementia by up to a decade, let alone all the other things.

Still, the point I was making is that it is not shortening her life; it's either having no statistical difference or extending it.
