Everything in Material world is temporary.
There are so many dangers in life because the material world is a place of danger.
The real problem of life in the material world is to solve the question of birth, death, old age and disease.
Srimad Bhagavatam 2.3.2-7,
If one team wins the world cup, dozens lose. This shows that in material world ratio of people suffering is always greater than ratio of people happy
Do not take this material world so seriously because it is always changing, what you take seriously is being some thing terrible today. Tomorrow it's Going to Change.
