What is in a name?

What may appear as a simple semantic debate (e.g. is aging a "disease" vs simply part of "normal species functioning") is, IMHO, one of the most important issues facing public health and biomedical research this century. It could mean the difference between investing billions of research dollars into the scientific research likely to increase life expectancy by simply postponing death vs increasing healthy life expectancy (that is, adding more years to life vs adding more life and years to life).

Cheers,
