Factors such as genetic makeup, the ability to reach medical services, and the regulations established by governing bodies collectively impact a person's life duration. While these elements hold significance, individual variations and random occurrences also play a role in causing deviations in the anticipated lifespan.
The rate at which harmful substances have been exposed to the environment due to industrialization is also a key factor to consider because it has a significant effect on the life span of humans. The type of food, water, and improper medical treatment are also factors that may reduce life span; poverty is also a factor because lack of proper maintenance and proper food intake due to a lack of money also causes sudden death.
