generational curses
This isn't Bible, but I think it's worth considering. If you don't think so, please be kind to the newbie, that is, don't kick me without warning, or yell at me--I do tend to get my feelings hurt a bit. ops:
I read some years back about a study on memory engrams, that is, chemical encodings of memories, which do not seem to all be in the mind, but located throughout the body.
In this study, a species of seagoing worm was conditioned to respond to a light source by the application of electric shock. The light would go on, an electric current would be fed into the water, the worms would respond by curling, and eventually, they would curl when the light came on, just like Pavlov's dogs would salivate when they heard the bell.
Nothing unusual about that, but here's the twist: when the worms were killed and fed to another set of worms who had not been conditioned, they too responded to the light.
Is it possible that something of grandpa's pecadilloes came down in some way we don't understand?
