I'm nearing 40 and am getting increasingly worried about what would happen if I were to get seriously ill (no foundation for this, just general worries about getting older!) I am thinking about health insurance and critical illness insurance but have no idea where to start and what to look for... any advice? Is health insurance worth it in the UK with the NHS? I keep hearing different things. It also seems very expensive from what I've seen and I don't have lots of disposable income, but am scared of getting ill and having to deal with illness and financial worries. Thank you!
