Depends what you mean by 'life.' Are you talking about this particular presence in the physical body you now reside in and will eventually shed? You mentioned the word 'your', so you're not talking about Life with a capital L and referring to this incomprehensible phenomenon The Life Force which appears to permeate everything and every thing (even rocks are made up of dancing electrons, and this movement must be life)
In the first of these, I must be well into my last quarter. I'm seventy-five in April. In the last of these, I am a segement of this huge Life Force - or at least this is my contention - so I am really immortal. I am the life, not that in which it is contained.
Oh, and yes, I do believe in Reincarnation. Living a 'life of quiet desperation' which comes to nothing makes no sense at all to me. But I'd better stop here. Afterall, I've said enough about these things in the numerous Hubs I've written in past sixteen months.
