What is something that connects Life and death?

It depends on how you interpret life and death.

According to me,

LIFE is suffering , and when we have suffered enough for our sins, we face death.

DEATH , in true sense is when you get free from the cycles of birth and rebirth.

So , what connects life and death are the GOOD AND BAD DEEDS we do during our cycles of birth and rebirth.

if i have to guess something totally different from these other answers i'll have to say it's inevitable because anything that is going to die or is dead had be alive at one point in time so life was inevitable as well as death so in a way that connects the both of them it's like for one thing to happen the other had to happen so they work in harmony even if they are quite opposite (u get the idea)

Death is between two lives your life now and another after death.

Birth.

Deathbed

Time

Breath

Maayaa

Pacemaker!

Every life ends in death.

That is the only relation.
