We began as a species focused on making sick people healthy, and it's the way the entire system works. It's near impossible to get studies approved that tackle aging and proactive healthcare with drugs, as they will largely need to look at the effects on people who are healthy now, but will almost assuredly die from dementia, Alzheimer's and heart disease.
I understand why it is the way it is, but it's frustrating to see the system wait until you have heart disease in your 70s before doing something about it.
