A curiosity about one’s past is always been in people’s genes. While family history can tell useful information about the medical conditions or habitual effects, current and future circumstances are more important than the past, because the current situation is different from the past to be based on. While I understand that presents are more important because historical gene issues can be prevented and cured by regular check-ups by modern technologies, the history of the family tells necessary information about the critical conditions or specific behaviours that people may not be aware of. So, people can make adjustments in their behavioural acts in this present phenomenon which could affect the future.
