In general, I'll tell you, there have always been pragmatists who seriously explain love as sexual desire or hormones... Poor people deprived of life, what can you say :)

It is not a fact that they are poorer and more deprived than those who explain it in other ways... At least materially, they are certainly wealthier on average. Love is the strongest (even too strong, monstrously strong feeling) and under its influence an egoistic person can commit various idiotic acts, which can lead them to very unpleasant consequences... and when the feeling of love finally passes, they will remember what they did under its influence and be ashamed and even horrified by it. In love, it is important to know how not to let oneself go... Simply when it seems that if not with the loved one, then living is foolish, absolutely pointless, behavior can easily become inadequate....

P. S. And generally, somewhere on the forum there is a topic called "Love - happiness and pain."

And can love be built? Is it a house?

Well, there is a show DURDOM2 where that's exactly what they do... I don't actually watch it, so I don't know how their progress is... and those who watched it before discussed it a lot, but I still haven't understood if anyone managed to build anything there or not idk...
