Interest and Gambling

Do we receive interests from conventional banks or dividends

Q: My question is that do we receive interests from conventional banks or is it dividend?  As far as i know, conventional banks use our money to invest and the profit received is shared among clients. Now, the money may have been invested in companies which we do not know if they are "halaal" or not.  But the question remains that is the money received is called dividend or interest?

Compulsory Health Insurance

Q: I live in a country where health insurance is compulsory. But the fine for not being insured would be less than the fees for being insured I think. On the other hand we wouldn't be able to pay my mothers treatment otherwise. Plus I think my wife is pregnant. And the costs that come with that also I wouldn't be able to pay without health insurance. The only alternative I can think of would be not to register her here but keep her registered in her home country and let her be treated there. But that would cause a lot of difficulty for us. What shall we do in this situation?
