Unfortunately, you can't take an 50-something english only American and tell him to "go learn Italian", for health. It's hard enough to make people eat less, exercise, or quit smoking - picking up new language without another motivation than "for health" is going to be even harder.

Most schools introduce more languages today, no ? And I guess there is no motivation to keep language skills active beyond school, so any skill here will likely atrophy like me French :(
