I seem to recall the
JTAS article in
Issue #19 on rejuvenation techniques, which was offered as an "Alternative' to costly, addictive anagathics..
by Robert Reese's " Gerontology, rejuvenation & the INterstellar Traveller", pp 6-7.
These were set at TL-13, for a minimum tech basis to do or better, with an UWP A or B-class starport, UWP pop 3 to pop 8, UWP Law level 9 or less world.
Persons undergoing such treatments were at the rejuve medical facility undergoing said "rejuve"/ renewal of their bodies for a period of 6 T-standard months, plus 1 month per decade over sixty.
Example 1a: An 80-year old traveller, would spend 6 + 2(decades) months in this facility just feel like & look, be as healthy as he/she was at 50 again.
Example 1b: The 80-year old traveller wishes to be younger still, say in his 20's, then is spending 6+ 6 (decades), or 12 months at the facility.
Persons qualified to start these treatments had to prove they were 60 years of age or older.
Base cost was set at 15Mcr plus 5Mcr per decade over 60.
In example 1a, the Traveller would have paid 15+ 10MCr = 25MCr total for his eight month stay and rejuve, or the cost of an S-class Starship.
In 1b, he would have paid 45Mcr for the 12 month long treatment.
While Mr reese's article points out the interesting concepts of such a society of gerontology, and the high medical costs developing a classical case of "Haves" vs. "have nots" here, there also should have been an implemented ceiling based on the original character rolled up IMO of where to set the limit how many times, a character could physically be "rejuvenated" before final death.
The costs alone provide that only the continuously wealthy could afford it, naturally. My take on that would have been to suggest use of the Player's Endurance/ Constitution Score (for those using the 2d6 way of chargen) divided by two, and for those with 3d6 chargen, the Con, divided by three for a simple solution and sane ceiling limit.
that's all I recall on this..
helpfully yours,
