Was I a gaming God when I was younger?

Now that I'm pushing 30, in a fit of nostalgia I bought several of the old style games from the Wii shop channel, such as, Mega Man 9, Contra Rebirth, Gradius Rebirth, etc. Man do you lose your edge as you get older. I can remember finishing Contra in maybe a days time. Now here it is my 5th day of playing it and I still can't get past the 3rd boss. Same thing goes with Mega Man. It took me the better part of a day just to struggle my way to reach and take out Galaxy Man. As much as these games frustrate me today I almost can't believe I enjoyed playing these difficulty fests as a kid. Has anyone else come to this realization too?
