Is 1 year health policy cumbersome?

In UK health policy is sold with long term perspective but in India we sell it with 1 year perspective.Our present system is more on US pattern.

For having peace of mind the customers will be happier with 10 years plan but with fixed rates known to them.This is similar to fixed interest rate vs floating interest rate.

Recent increase in rates by New India/United -for higher age group going up by 80% or so has really shaken the confidence of the insured .
