I don't think there is "living" life after death.

When your dead your well, dead!

The only way to live after death is to create a legacy - or at least do something people will remember you for rather than just fade away.

I'm sure everyone has this "great great uncle twice removed cousion brother" who did something outrageous or has a blinding claim to fame.

If there still being spoke about then they live on.

On another note the mind is a very powerful thing and I do beleive in higher planes of thought and conciousness. I've been there!
