That sounds fascinating - I'm going to have to look it up now!
I sort of do that but I'm used to living on my own - I talk to myself a lot but usually just in my head and when I'm reading or crocheting I don't generally talk.
She's a golden doodle and I think about 5 years old. We've done a walk of about 3 1/2 miles today (with a lunch break in the middle), the other days we've probably done around 2. I am definitely getting more steps in! I am enjoying having her, I was told today it 'suited me'. At the same time it's a lot of responsibility and it makes me think I'm probably pretty selfish (or just very self-sufficient!) the rest of the time - I'm finding it a bit weird needing to take someone else's schedule into account.
It really is! It's hard when the pressure comes from others too (even unintentionally). I find that friends/family will say 'you shouldn't be working that long, just do what you need to, don't obsess over things, don't do the 'nice to do' stuff only the 'need to do' but sometimes I really am only doing what I need to.
