Poor advice - hopefully no one will follow your lead! Lying to an insurer is pointless and you may as well just not bother getting insured.
If someone lies or misleads their insurer and then gets found out, not only will any payout not be met but the insurance is cancelled and you then have to disclose to all your other insurers that you gave had insurance cancelled. Result - things like home snd car insurance are either impossible to secure or the price rockets.
I have a friend in this situation currently and what seemed a small issue is now snowballing.
In terms of whether something is worth paying for, each person will take their own view, won't they? When we took John's mum for her final trip to Australia the insurance was over £4k - far more than her first class flights were costing! She qas ill and our view was that 4k was worth every penny to give us peace of mind.
I don’t think you can make such a sweeping statement about policies costing less than £200. Some men will have full cover for less than that, others will pay more.
