I wonder if this can be connected to a fatigue that I experience during clothes shopping. Whenever I enter some kind of a clothing shop I get super tired after 10-20 minutes of searching for something, while my girlfriend could do that for hours on end. (I hate shopping in general it just makes me tired :( )

I love both museums & shopping, but I also tire of both after about 20-30 minutes.

This is why I have memberships to my local museums, I'll pop in for 20-30 minutes at a time and be content, and not feel like I have to "make use of" an entire entry fee.

Time to move to London, will save yourself a fortune :)

Or Washington, DC. The Smithsonian museums are world-class, and free.

This has changed a lot for me as I’ve grown older. I used to have this really bad but it has faded slowly.

For me its also physical. My legs get more tired waking a few hundred meters in a museum than just walking kilometers outside.

I’m the same. My wife loves museums. It’s been a long 22 years.

I always thought it was because I had a character flaw. Like I’m not cultured enough or too stupid.
