good question. malapit na akong mag-30 at karamihan ng mga nakasabayan kong tumutugtog nung college, pati mga batchmate/tropa ko nung high school na tumutugtog, matagal nang retired sa pagbabanda...they've mostly settled down and started families and focused on their "real" jobs...
...pero ako, siguro itutuloy ko pa rin ang pagbabanda ko kahit kasing-tanders ko na sina mick jagger, paul mccartney, etc. you're never too old to rock, and anybody who thinks rock is solely for the younger generation can stick that up their behinds...
