What is the life span of a Schlumbergera gaertneri Easter Cactus?

The Easter blooming cactus [Schlumbergera gaertneri] is a successful houseplant. So it can live for many years if its environment supports its needs. It's a jungle cactus from Brazil. So it's the opposite of the desert cactus in its needs.

Specifically, the Easter cactus isn't used to direct, harsh or strong light. That's because in its native environment it's light deprived. The tropical forest is a thick, dense, dark place for a growing jungle cactus. What it lacks in light it more than makes up for in moisture. It handles warm, humid environments. So it won't live long if it's subjected to long hours of direct or strong light. Neither will it live long if it's put on a little or no watering schedule.
