I found that as I get older, and still try to learn different languages and platforms, that I have to try and work on my research skills as much as my coding skills.

As the OP pointed out - straddling several languages means that syntax and keywords are not always readily apparent when you sit down to code, but knowing where to look for them and refresh your memory quickly becomes an activity all on its own.

This from a guy who is a week away from being 50, and still occasionally puts a ';' at the end of his ruby code blocks.
