To Fall in Love

There's been a lot of talk recently about a 20-year-old study by Dr. Arthur Aron on how to make people fall in love.  My takeaway is that, if the process is one that can be quantified and chosen, at the same time it's also frighteningly easy to undertake.  If merely asking probing, personal questions and making extended eye contact can do the trick, shouldn't we be a bit warier about these actions?
