Realization: Time left with parents only 50 or so trips left

As I live abroad in Japan, meeting my parents is not as easy as it used to be. Since I have relocated to Japan in 2020 Feb I only had 2 to 3 chances to go back each year. More closer to two taking into account that I haven't been able to fly out due to Covid for close to two years between 2020-2022.

After spending a few days with my parents on the flight back to Tokyo a simple arithmetic hit me hard.

There is only a mere 50 more trips left for me with my parents till death comes in do us apart. Even less if something unfortunate is to happen.
(Assuming I manage to make 3 trips a year and my parents are in this world until they are 85)

A wave of sadness.
So limited is the precious time to spend together.
Something pretty obvious but I haven't really faced with all seriousness.

I need this reminder for myself and visualized it. Every time I go back home, i plan to cross off a circle. Whenever I feel the urge to open the email on my work phone during holidays or feel like I need a distraction to read articles, watch youtube videos while spending time with family I will try my best to look hard at the remaining circles so that I cherish and savor each time as much as I can.
