Seeing family getting old is hard!

I spent good 12+ years away from home, and I am back in India for the last 5. I am not the closest with my father, but it is very hard to see him get old and not in the best shape. My mother is older, but still very fit and active.

I understand that getting old is the virtue of life, and it is coming to all of us. How does one balance your personal / professional growth agenda w/ aging parents? I feel guilty sometimes that I am not there for them as much, even though I am in the same country.

Anyone else go through this?
