Wow reading about pensions my mind just assumed you were properly old. YOU ARE ONLY 38?! Congrats on the financial stability!
I also have moved around a lot, mostly for work, all exciting opportunities. The first few years going home feels like nothing ever changes but I recently went to my home town for a wedding and saw some friends for the first time in 15 years. Wow did the passage of time hit me like a truck. The years add up.
I was in the mountains hiking with an 85 and 82 year old a few weekends ago. They crushed. We may be older but we are still a lot closer to 18 than 85.
One comment I heard from a native french speaker is that the “dictionary is much larger” than french. Which makes sense because English incorporated many french words.
