Love: Cheesy, yet Interesting

Yes, I'm addressing it, I've been trying to post intellectual, and interesting topics, but during the holiday love is supposedly everywhere. You see it in all the commercials, the man getting just the right gift for the woman he loves, or the woman doing the same for him, or whatever those brilliant marketing people can come up with to cram love down our throats. Yes I'm sure love is a wonderful thing when in it, but what about those of us who aren't. Its an annoyance to see all these happy couples everywhere you turn which reminds you how lonely and miserable you are. This makes me wonder however, why do we seek love, whats so great about it, and what is it? Well to answer the first two questions, one must first answer the third, what love is. Love is obviously good, otherwise it wouldn't be universally sought after. Love must be healthy, those who lack it are often unstable, depressed, or likely to have other disorders. Love must be an intellectual pleasure because it is intangible, it must be thought about, considered and appreciated, and its benefits are not limited to an amount of time. Love is not directly related to sex, some may love, but have no sex, while others may have sex and not be in love. Love however may enhance sex, along with any other activity in life. Therefore love can be defined as an intellectual pleasure that enhances the lives of the people involved, and is universally good. So why then is love so great? Love perhaps is so wonderful because it is one of the few things without a detriment. Usually in life there is always give and take, in order for the rich to be rich there will be poor people, for a heart transplant recipient to live another person must die, these trade offs can be found everywhere, but with love there is no trade off. Some may say the monogamy of a loving relationship is a sacrifice, if say I was going to marry a woman I loved I would be giving up the chance to be with countless other women. However if I am truly in love, then it isn't a sacrifice since I have attained a universal good, which is benefiting me, and furthermore, if I was truly in love with that woman, any other woman would most likely be inferior and would be no real loss anyway. So why do we seek love? Why do we turn green with jealousy when we're single and actually looking for our match? Well why are we jealous of anything? Love, being such a beneficial and good sensation or experience we of course want it, just like we want food when we're hungry, or drink when thirsty, we need it. I'll admit, it is difficult for me to talk about love, being single, and never having experienced true love in any of my relationships, however I think its a gift, my condition that is, so that I may see what others do, and feel when in love, and maybe understand it as a scientist studies something, from the outside, impartial, evaluating every aspect.
Hopefully some people who are in love will read this, and possibly be strengthened by it, or contribute comments to their beliefs on love. I know it is a cliche' topic, but it is interesting, and something we all eventually search for.
