I think the ideal length of my life might be around 27,375 days!
Living too long doesn't seem like a good thing. If my sister and partner pass away before me, living alone in this world would be quite lonely. So I don't want to live too long.
But living too short is also not good. It would make my family sad. I always feel that it would be more appropriate to die a few months after my family members pass away, so that everyone won't be in pain.
By my calculation, living to around 75 years old would be just about right.
