I don’t know what you think you are getting at with this, but it doesn’t mean anything. There are many forms of exercise that are highly targeted and there are many drugs that have multiple systemic effects (Mounjaro being an excellent example). But in any event, the clinical purpose of both exercise and medications and indeed all health interventions is to extend healthy life years.
If you talk to a medic about “life to years and years to life”, they’ll recognise the phrase straight away.It’s just a nice easy lay person rendering of QALY. And QALYs are well understood as a means of comparing the impact of health interventions, and increasing QALYs is a goal of health organisations around the globe, which is what you’ll immediately notice if you google the phrase.
This is my specialist professional field, by the way.
You also made out that I was making some weird point that technical terms don’t matter in medicine! They absolutely do, prevention matters, exercise matters, healthy living is vital, but clinical interventions are not entirely separate from them. I am in awe of the technical brilliance and sophistication of medicine.
I will give you just a single example of how these things interconnect: I broke my ankle climbing last year (well, landing badly from a fall). I needed an operation and my ankle was pinned. The intervention was exceptionally technical, I had a bunch of drugs and all sorts of other stuff and my recovery involved not only physio (ie exercise) but also tapping the inflamed area and mobilising it as soon as possible — massively different from standard practice of just a few years earlier. The surgeon explained that tapping the area helped push water molecules that were accumulating in the affected part of my ankle through the inflexible lattice formed by tendons and ligaments, and thus reduced swelling and enabled quicker recovery. It worked, too. I was able to walk after six weeks and was fully mobile after 12. Some of the intervention was thus super-specific, some was broad, some was “clinical”, some was “health”, all of it was useful and all of it added life to years for me (ie little impact on my mortality, but lower morbidity during the recovery period). What was medicine and what was exercise? Utterly unimportant to me - all I cared about was that the interventions were backed by an evidence base, feasible for me, and worked for me. It was, they were, and I’m grateful every day, especially because I’m actually stronger and more flexible than I was before.
