Negligible senescence after 60 (or 40) years is not actually youth. It's past reproduction age for most people.

"Negligible senescence" means that you don't get appreciable deterioration with age. You're 240, but you feel 29.
EDIT: Ah. They explain that later in the article. That's an unfortunate use of the term, given its history of use in the field.
The article considers four separate cases: 1) negligible senescence, 2) slowed aging, 3) continuous rejuvenation, and 4) one-time rejuvenation.
It seems that at least 1 and 3 are what you want. Have I misunderstood your comment?
EDIT: thriftwy is correct, here. The authors leave the crucial detail of when, in their model, life extension begins, until deep in the article. It's around age 60, in their model. This is in no way what is conventionally meant by these terms as I have ever seen them used when reading about "negligible senescence," "anti-aging," "SENS," & etc.
