Hi there
Whether or not it's risky to not have health insurance, depends on the individual. For example, if this person has a family history of a particular medical condition, it may be wise to obtain insurance - but it's a personal decision.
If this person has an income of about €200 per week, he is only slightly over the medical card income guidelines (€184 per week). He is however entitled to claim reasonable expenses in relation to rent/mortgage costs and weekly travel to work costs in his medical card application. Claiming these extras might mean he will qualify for the full medical card.
Again, on the basis of the information you supplied, if his income is €200 per week, he will qualify for a [broken link removed] in any event.
