I'm saddened to hear of your deep loss Kevin,
I don't believe in a God in heaven or Angels talking to the souls of the dead or men in clean red suits clambering down my chimney in late December. As far as i can tell the purpose of life is life. We delude ourselves in all kinds of ways when we go beyond that pure and simple thought but often our own stability and survival demand we take respite from lifes hash realities or take on desires and wants to make life worth living. Biologically i have been surplus to requirements for some time now, having replicated my faulty genes some years ago but will spend the next 40 or so years enjoying as many days as possible, reading, swimming, working wood by hand etc..
best wishes, unclebuce
