Bio-mechanical Enhancement of the Human Body: What would you get?

I'd take artifical joints, muscles and bones, to make sure I can't be harmed and to boost my strength and endurance a bit. I'd also love a photographic implant for my eyes. I could "take a screenshot" of something important, such as a speech or a shopping list, and recall it anytime.

I'd go for a more advanced control mechanism for my body, aswell - for direct customization of my bodily functions, to be able to adapt to all situations. For example, disposal of heat by breathing out hot air instead of sweating during hard physical work, when I'm wearing something I don't want to sweat into.

Jam it back in, in the dark.
