She feels like it's too long paying the premium till 80yo

And the CI is kinda low
"Any further financial background about herself ?" Such as?

The projected sustainability is provided you continuously to contribute 200 monthly until 80 years old otherwise it may not sustain till then. Unless you're willing to pay 2x - 3x more premium now in order not to require to pay after X amount of years and it will self sustain thereafter, not accounting if the fund performance is bad / increase in medical inflation cost / etc factors.

As for CI, depending on her annual income, it will be best to have atleast 3x - 5x of your annual income minimum.

Which is why more info about herself such as her current income, phase of life, dependents, current investments, cash on hand. assets, liabilities will tell me more about herself.
bro, I think the highlighted statement mentioned is incorrect especially the current regulation requires all insurance companies to show how long a policy is sustainable in the annual statement every year.

By telling the client to not continue making the regular monthly premium payment after [25 years later] will be detrimental to the insurance policy especially medical policies would constantly be reviewed for increase in cost of insurance, what in this 25 years time or 50 years later, this person will certainly be required to do a top up from time to time if that happens, what more to suggest that they could stop making payment after 25 years later.
