I'd appreciate any feedback,
I agree with the others when they suggest that you not normally change your playing style based on the age of your opponent.
The only edge that you might have against an old opponent is in the area of concentration. Older players have a harder time concentrating for sustained periods of time. So it's not unusual for an old person to play worse near the end of a long playing day. (That would also apply to the late rounds in a one-day tournament.) At the end of a long day of concentrating, old guys' brains tend to just get fried, and they're more prone to make mistakes.
So if you find yourself playing an old person late in the day, you might try to prolong the game, as long as you don't have to change your style or make inferior moves in the process. So if you can't quite decide whether it's time for you to resign a game, you might want to keep playing a bit longer than normal, hoping for a "concentration" blunder by your opponent. Or, if you can't decide between a simplifying move or a move that maintains tension or complications, you might want to choose the latter.
