We often see photos of celebrities that look so flawless, it's hard to believe they're even real. Before you start comparing yourselves to them, keep in mind that their photos are usually photoshopped.
Everything happens for our own good, there is science involved and reasoning behind everything. Nature has its own ways and tricks to play with everything but that is just how it works. This is just how our world goes around. We should not think of ourselves as omnipotent and mess with nature because human beings are not perfect, therefore, whatever we do no matter how great we become it still can not be as good and perfect as the natural, original thing.
