Aging

Just now, my aunt and I accompanied grandfather to the clinic for a body check-up.
I suddenly realized how hard it was to take care of an old people.
Grandfather got stroke last year.
Grandma had lost a lot of pounds taking care of him...
How heart-aching...
It seemed like the one who took care of someone suffered much more than the one who was taken care of.
My aunt and I were frustrated to see grandpa's attitude. He was lazy to put effort on walking and other movements.
He was not willing to use his own energy to make himself healthier.
I wondered this was because he was already tried his best or just wanted to depend on grandma in the rest of his life.
Becoming old is natural... but would there be someone around you, taking care of you willingly when you are sick?
To be honest,
I... I don't wanna be alone when I become an old woman...
