I don't like to think so, but there may be something to it - not sure what.
I know of our two sister cats, Elfi died first, and she was by far the most intelligent, and adventurous in all matters perception, like taste.
I don't think Paul is long lived due to his being conservative - if you look at them, you can see he has a 'solid' etheric. One can have a solid etheric and still be adventurous. But adventure does bring its risks. Paul never interested me, I must say, and yet, I have no attraction for those wild 'out there' performers from the 50s, 60s and 70s who in their older age look like death warmed up.
I hold that one can do both - have an open and a solid soul. I use myself as an example.
