Which type of information should not be stored in ROM for a lifetime database?

The rationale for selecting weight as the type of information that should not be stored in ROM for a lifetime database is rooted in the nature of that specific data. ROM, or Read-Only Memory, is typically used to store data that does not change over time, such as firmware or critical system instructions. Lifetime databases are intended to hold information that remains relatively constant throughout a person's life.

In contrast, an individual's weight can fluctuate significantly over time due to various factors such as age, health, diet, and lifestyle choices. Given these fluctuations, weight is not a stable piece of information suitable for permanent storage in a system designed for lifelong data retention.

On the other hand, birthday, name, and city of birth are generally considered to be static or unchanging information once established. Names and birthdays, for example, remain consistent through a person's lifetime, and city of birth does not change. Therefore, they are appropriate for storage in a lifetime database, while weight should be excluded due to its variable nature.
