>Is kissing good for you?
yes
exchange of antibodies through kissing is long known and the strengthening of the immune system well researched
it's also (speculated) to be one of the factors why married men live longer
and anecdotally, I got less sick once i moved in with my wife from a long distance relationship

highly doubtful about that
Alzheimer is a relatively "new" illness
and cases doubled in the last 20y in the industrialized world
while EBV prevalence rate is unchanged
people have been kissing for millennia
