Children are up to five times more likely to get lead in their bodies, so under no circumstances should children get leaded tin in their hands.

It is possible to get lead poisoning through the skin even as an adult if lead is handled daily. Fortunately, nowadays lead-free tin is used, but I know that some hobbyists still have a lot of lead in their stores.

You need a big centrifuge where you can live or at least sleep and do physical exercises. It should eliminate the health problems caused by low gravity.

Majority of geothermal enery comes from the decay of radioactive isotopes. It's not renewable, but there will be enough heat for millions of years.
