- Everyday life
Sodium nitrite makes cured meat safe from botulism and is associated with nitrosamine formation. Removing it would reintroduce a lethal risk to remove a statistical one, which is why it remains in use.
- Technology & computing
Ferrari 250 GTOs have sold at auction for sums exceeding fifty million United States dollars, among the highest prices recorded for any motor vehicle. Thirty-six were built between 1962 and 1964.
- Geography
+250 reaches Rwanda, one of the most densely populated countries in Africa. Its post-1994 reconstruction is widely cited both as a development success and as an authoritarian one, and both readings are argued from the same record.
