Age 32, Self-employed, 2 lacs/annum, can my dad invest 3 lacs in postal MIP with no tax burden on me?

I am working in BPO as a free-lancer in India. Recently I heard about Indian Post Office MIP being a good option for monthly income. In fact, would like to know if any other such equally safe option is available to me too.

My question is if I can ask my father who is a retired govt service man to invest around 3 lacs in my name so as to the interestes accrued can be used by me. But of course, would not like it if it gives me any extra tax burden. As of now, I have around 2 lacs/annum of income against which I invest in LIC/PPF to the extent of 60000.

How do I choose a suitable mediclaim policy?

I want to get a mediclaim policy for me (age 34yrs, Indian) and my wife but I do not know how to choose a particular insurance policy. What are the factors one should look for before deciding? In fact it seems that many companies offer more or less the same benefits. Should I go for public or private sector company? Are family floater plans useful for tax saving purpose as well?
