For example it should say "5504 6th of decembary" in tooltip and in 'i' - For anything in health tab, including prosthetics, missing parts, scars, wounds, immunity (contracting disease)..
As well as clearer descriptions of effects and influenced body parts. For example, with "withdrawal" both the 'i' button and the tooltip aren't giving anything, but flavor text, even though, when hovering over moving/consciousness/etc - it shows 'withdrawal x%".
