Don't worry about what they do or don't.
more times than not God simply slaps you down (and we call that bad luck!) and the really amazing things that happen-like your child's birth-are the few times God's even gonna bother with you
I say "thanks god" everytime I eat, knowing that some poor soul on this very planet will cry out for any morsel of food that moment and expire from starvation when it doesn't come. There is a verse saying The Guru is the source of all nourishment, sort of God's distribution network. Thank you God that I eat well and process easily what I eat! :)
Getting older is no problem. You just have to live long enough.
