For pretty much same reasons you mentioned. There are a couple of factors that I also think impact the development of hobbies:

1) Did you learn them as a kid? Parents that taught their kids to golf, ski, snowboard, surf, etc give them a real leg up in their chance of having adult hobbies. My family was poor so we didn’t do those things and my dad worked 6 days a week to provide a meager existence for the family.

2) Do you have a lot of support from extended family? We don’t. So that made it hard for me to feel good about telling my wife I was going to go play golf or ride a bike for 4-6 hours on a Sat while she was grinding taking care of the kids all week without any help from grandparents, siblings etc to lighten the load a bit while I was in Med school/residency or at work.

3) I really value and appreciate the influence of the church in this phase of my life. While yes there might be more time for hobbies without church service, the influence it has of getting me outside of my self and bringing me to Christ in ways that I couldn’t easily do on my own are invaluable.
