The time after the present. You can't be sure that death is certain for anyone alive at this moment.
I am %100 sure that everyone will and should die eventually. Never said it'll happen now, as the time passes we all approach to our inevitable, absolut end.
I am guessing you are implying death is not certain because as time develops, there may be a chance to be immortal by advanced medical science.
Considering the money gained by people dying, I don't think thats likely to happen soon. I am %100 sure our generation wouldn't see that.
You buy food which has additives to increase free radicals in your body which causes cancer.
You buy treatment to overcome cancer which also kills your healthy body parts
You buy treatment to cure sideeffects of cancer aswell
You die.
It is an example of many common ways gaining shit tons of money by getting people dead. To achive immortality, humans should overcome their ego and probably get monatary system out of their lives which is a fucking distant utopia.
