Sure, if I don’t want to live because my life is insufficiently healthy, one solution is to keep making me healthier until I change my mind, then extend my life.
More generally, if I don’t want to live because my life lacks some property X (of which health is one example, but not the only one), one solution is to provide me with X and then extend my life. I’m not sure I would consider the general problem of providing people with everything they lack to make life feel worth living to them be part and parcel of life extension, but it’s not clearly wrong to do so.
