Every European (and I guess non-Europeans as well) can vote what our next Euro design will be: https://surveys.ecb.europa.eu/10b/neweuro/
About ten different designs are available and about half of them feature birds instead of boring people.
I really like the bird designs as they symbolise freedom without borders. Hope one of them gets chosen in the end.
It is extremely difficult for elderly (or anyone) with rheumatoid arthritis, arthroscopic injuries or just deteriorated hand grip, as most windows require a strong two-handed grip to open, tilt or close. I love them, but my elderly relatives require help from us relatives or home aides/helpers to even manage to ventilate their homes.
