My nose seems to be getting bigger or growing the older I get

As I’ve gotten older it seems that the tip of my nose has drooped more and more. Is this something that can be fixed with rhinoplasty surgery?
 
Yes.  You have normal senile ptosis.  Almost everyone experiences this to some degree.  Its one of the reasons the nose looks larger with age because it drops and looks longer. There are techniques for improving the droopy nasal tip without making it look like a snout of a piggy nose.
