If your native language isn't English (or even if you're outside the US) I wouldn't recommend DDG for older people. They'll want to search in their language and most searches will be about local stuff and DDG sucks in that area. It's my main search engine and I constantly play with the country toggle but if I want something actually local I usually end up switching to Google for this search. Just make sure to install an adblock so you avoid the "Ad" results.
