Definitions

A Future Longevity Catalyst is defined as an event with the following properties


(i) An event which has not yet occurred
(ii) Its occurrence or non-occurrence should be unequivocal and take place at a unique point in time.
(iii) Its occurrence is widely expected to lead to a demonstrably significant and positive effect on the overall life expectancy of the associated population.

A Past Longevity Catalyst is defined as an event with the following properties

(i) An event which has already occurred
(ii) Its occurrence could lead to or has led to a demonstrably significant and positive effect on the overall life expectancy of the associated population.

For the avoidance of doubt, whilst the occurrence of such catalyst events is required to occur at a point in time, the corresponding effects on life expectancy are expected to be realised over an extended period of time.  Past Longevity Catalysts may therefore have significant future repercussions which have not yet been recognised.
