in the messianic age of Saturn, we will be able to change our physical appearance.

still trying to figure how it would work...
DNA is encoded light, so I think perhaps with the fully activated pineal crystal (refer you to my thread "operation light to the nations") it would be possible to "shed" light using our pineal to manipulate our DNA from the inside.
or it would be a different method all together, where actual crystals are used to beam light onto a person, and alter his genetic structure from the inside.

one thing I know for certainty, drinking the waters that will flow out of the third temple will change our appearance, and improve it... to some degree, nothing too serious though.

the real major changes will happen through light dna manipulation.

all Torah divine technology, no poisonous evasive genetic science.

since the messianic age is basically making up for the time we were supposed to spend in the garden of eden.
and Adam and Eve were the most beautiful humans to walk on earth, and we are degraded copies of copies of copies x2000 of Adam and Eve.
we will gain the knowledge of restoring or DNA to adam and eve state...

it is G-d's will that his creations will be perfect and happy.
