The kill of change

Sometimes i wonder,can humans get younger?If so,can we get better lives?Can we change society?Would we be able to modify our looks?Would companies shut down because no one wanted to buy their beauty products?I just sat down and thought about all these things.Change may be good,in good and bad though,there are two sides to the coin.One good,one bad.If it was all good,then it will really not be a coin of change.It will only be a coin of everlasting uncomfortableness,for no human can endure this.....this bliss,this ultimate change.In one moment,I just wondered......if humans could change the oncoming global warming,then would scientists worry until their hair grow white,with patches of grey wticking out of their heads like 2 antenatte?Would our lives be better?Would it?Would it......?
