ScienceDaily reports yet another study that shows that solving puzzles such crosswords or Sudoku has a positive effect on our brain. Tl-dr: regular puzzling makes your brain about ten years younger.
Previously we have discussed the effect of lead exposure on cognitive development as well its association with crime. ScienceDaily reports a new study that further confirms the negative effect of lead on neural development:
Bottom line: any concentration of lead in the environment has a negative impact on the cognitive abilities of children. Since this damage is permanent, lead poisoning is a major social problem as reduced mental capacities will negatively affect performance at school and in later life.
Hence our position remains that the authorities in future space settlements should implement a zero tolerance policy when it comes to lead – any lead containing product should be banned from daily life.
