Who still uses a handkerchief?

My SO and his parents use cotton handkerchiefs. I haven’t seen a person carrying one in years for the sole purpose of blowing their nose, thanks to disposable tissues. Sure, bandannas are still used, although it seems more for decoration, code or as a headscarf. Is it a cultural or age preference?

Should they make a comeback in an effort to be ‘green’?

And if anyone is interested, here is an article on how disposable tissues came about.
