Deciding to try for a kid with my wife. It seems like a huge commitment in terms of time and money, and I worry I won't be the best father. She thinks I'm awesome and isn't worried though, and it's something that she's feeling that she needs in life. So we'll see.
Quicken or other accounting software is an option if you want to track more than just your bitcoin stack.
L1 Bitcoin will work just fine on interplanetary scales, you'd just need to wait for extra confirmations compared with Earth time. Mining would only ever happen on Earth, though (maybe on the moon as well). Planets could have their own lightning networks.
All of that without a mention of kin selection as a mechanism for maintaining homosexuality in human genetics seems like an oversight.
