I quizzed pretty actively throughout my school and college life. Although the frequency of taking part has declined, I still love setting questions for quizzes.
I write here (more like used to write) on Quora and try to actively contribute to what I feel is a wonderful community. I write mainly on mathematics, music, soccer, and languages, linguistics and etymologies.
I've been playing the electronic keyboard (synthesizer, if you please) for 8 years now. I try to express myself through the instrument. Since February 2017, I've been playing the ukulele, and am falling in love with it a bit more, every single day. I have 3 ukuleles in my collection, a Diamond Head DU-150 Soprano, a Luna Tenor, and a Mitchell MUB70S Baritone. Among other musical instruments, I can also figure my way out around a guitar, Seagull Merlin, mandolin, Appalachian dulcimer, and a harmonica. I love Bangla Rock (see this and this to get an overview), hard rock, heavy metal, and progressive rock and metal. See my SoundCloud profile for some of my covers.
I formally learnt the game for 5 years when I was in middle school. Since then, I've been playing it at an amateur level.
