this theory doesn't make sense in my head yet

think about it. us elongating our lives could be the end of us as well,

if its a cycle, a circular one somehow? the largest entity would share the same cycle as the smallest would.

We grow up, get old, get smaller, then die and totally decompose, and our body is recycled down to the molecules, and even smaller. If we break that cycle, we could totally kill ourselves off
