If tomorrow the human maximum lifespan increased fivefold, what effects do you think it would have on our behavior or our outlook on life?

So instead of an approximate 120-year max, we would have an approximate 600-year max. (But let’s imagine that we mature at only a slightly slower rate, “adult” at 30-ish instead of 20-ish… since it seems cruel to say that “pre-adult” is now 100 years!) Note that this is the apparent biological maximum lifespan, not life expectancies.

So, we wake up tomorrow and every human has a five-times longer maximum lifespan. As we’d be the transition generation, only whatever potential lifespan we have ahead of us is affected (so at 23, I’d have a maximum of 97*5=485 years left, probably falling short by many decades.)

Yet everything else would remain exactly the same. Other species’ lifespans have not changed. The various sociopolitical situations in the world have not changed. Diseases would be just as deadly, but the onset of certain chronic conditions would be delayed. Etc.

How do you imagine this would effect how we navigate the world? What would become more/less important, more/less problematic, etc.? (Since this question potentially encompasses so much, feel free to just focus on the one or few elements/aspects you want to consider, as individual or as global in scale as you want!)
