Time right for Healthcare iShares?

[trof]

A couple of years ago I saw the handwriting on the wall and bought some Natural Resources iShares in my IRA and in my wife's. The growing demand for raw materials looked like a lock to me.

These iShares are invested in a wide range of 'extraction' companies; oil production, mining, timber, etc. They have done quite well, even throwing off some dividends once in a while.

Now I read that health care costs are expected to double by 2017.
Healthcare iShares have been in an upward trend since their inception, but with a slight downward drift recently. Right now they're selling at about the midway point between the 52 week high and low at around $55 per share. It looks like another lock to me.

Comments?

2. Probably the global.

But I need to do some more research.
