Since I was raised from infancy as a JW and was thus practicing the religion since very early childhood (until I cam to doubt and disbelieve it), becoming a JW didn't cause me to give up something I enjoyed. But practicing the JW religion resulted in me avoiding doing things which I thought I would enjoy and/or otherwise consider worthwhile. For example prior to getting my own home I didn't go on dates and I never went to prom (but my mom said it is up to me if go to prom or not; she also said it is up to me if I join the high school track team or not). I didn't read literature promoting atheism or non-JW forms of Christianity, and that made it much harder for me to see problems with the JW religion, Christianity in general, and the Bible.
Since I was busy with JW meeting participation (including giving talks), preparing for JW meetings, and with field service, I had less time available for doing what I liked (such doing science experiments and trying to make inventions, studying science and technology, and pursuing other hobbies).
Despite being a JW In my final year of high school I do join the school's science club and the school's computer club. I played a little chess.
Regarding aluminum cookware, at some point after age 40 I came to think it is probably less healthy to use that kind of cookware. That change in view was a result of what I read on the internet (but I read conflicting information about it). As result a number of years ago I replaced my 'nonstick' aluminum skillet with a stainless steel skillet, but I still use nonstick aluminum cooking pots, aluminum cookware lids, and an aluminum large spoon. Nearly all of the aluminum cookware was given to me by JWs (from a congregation I attended at the time) as housewarming gifts.
