A simple question, but your answer can be as short or as long as you like.
Great question, Margaret!
Hmmm… I wonder if we preface the title with SIMPLE - so that we can keep whatever Level you’re on in the brackets? Maybe that would cover both bases? ![]()
[And welcome to the green!]
I’ve edited the title as per your suggestion. 
Duolingo teaches myfyrio for “meditate” 
(Related to “contemplate, ponder”, so a myfyriwr “student” is someone who “contemplates, ponders” things or, if you want, “meditates” on them!)
Sut i fyfyrio …
Ma hynna’n wych! Myfyrio drwy’r Gymraeg 
That’s brilliant! Meditating through Welsh 
I hope it’s all right to answer your own question!
I’ll have a go at the others too, but I thought I’d start with how I like to relax.
Lovely to hear your answers, @GuyHill and @christineevans. Those are excellent ways to relax. 
Ti’n ffodus iawn, @helen-gwyn-jones! You’re very fortunate!
