Not really reactive with the chemicals in our bodies

Titanium
Well Titanium is an ultra light alloy and is available in various grades for various purposes. In the medical end, titanium (generally grade 23 or better) is used for hip replacements, ball and socket joint replacements, it is also used for screws pins and plates that are intended to be left inside the body due in part to it's bio-compatability. Which means it wont elicit an adverse reaction when used in the body (other wise know as a rejection).
A piece at a time, maybe; have your joints replaced with their latest Titanium substitute and by the time you're done with that, the rest of your skeleton may be available.

No, because titanium is relatively rare. If anything, they're being used for aircraft next to aluminum (aluminium). <<>> Titanium is as strong as steel and a lot lighter, but it's too expensive to use in large quantities. It is used in aircraft where strength and lightness is needed and the cost is not an issue. Titanium is also used medically to help repair broken bones and also in tooth implants, because inside the body it is completely inert, it does not react with anything or go rusty.
I'm sorry... but I have NO idea... However, I "Googled" it, and the search results are here: http://www.google.com/search?hl=en&q=titanium+dioxide%2C+bones&btnG=Google+Search Copy & paste the above into your browser... You'll get a lot of sites to research your question...
The lack of gravity and exposure to artificial gravity severely weakens bones.
Metal detectors cannot find gems or diamonds because they are not actually metals. Instead, metal detectors can find silver, gold, titanium, and other precious metals, which can be worth quite a bit.
Birds bones are hollow. That is why they can fly, because they are so light because of their hollow bones. x)
No because muscles move bones and are attached to bones.
insects shed their exoskeleton, not their bones because they have no bones.
