This is Kawaguchi Hidetoshi. This is my humble answer to the question.
My son will be 40 next month. That's no good.
“At 40 years, I think of it as my last specification at a good time. ” ・・
That's no good.
Certainly, living is truly equally difficult and difficult for everyone.
Of course, as I say, four struggles, not only about living, but also about old age, sickness, death, and the suffering of having to break up with the things and things you love, “grudge affliction” (onzo suffering) of the suffering of having to meet things and things you hate, and the “unrequited suffering” (unrequited suffering) of not being satisfied even if you ask for something (in substance), and the mental and physical effects of not being able to obtain it. There is a “five great suffering” (Goonjoku) of suffering caused by being there.
The Buddha is explaining the teachings to put an end to this suffering.
“What happens when people die?” ・・
It is one's own actions, work, and karma that have a big impact on one's whereabouts and flow after death.
As much as possible, I would like to move forward better and adjust the causal relationship (cause and condition, motivation and action) of good behavior towards a better trend. There is also a hint for that in Buddhism.
By all means, I am grateful that you have taken an interest in Buddhism, and that you have been working hard to practice even a little bit.
