I like silver. Jewellery. But did you know it has anti-infective properties too? Some patients get given silver impregnated devices to try and reduce their risk of infection (e.g. things that might have to be inserted into a patient’s bloodstream, where we don’t want to introduce infection).
I like carbon. It is very versatile, depending on the arrangement it can me graphite to diamonds.
From a biologist point of view- it is the key element for most life on earth.

I’d say oxygen. It’s very practical but I wouldn’t want to be without it!
