Baking – you don’t have to turn on the oven, so no energy costs, and no calories, better than Weight Watchers
Exercising – you won’t hurt yourself by overdoing, only imagining it is good enough to work off the nonexistent calories from eating the things you pretended to bake, and your fake shower afterward will be good enough, while saving hot water
Juggling – you can keep as many objects in the air as you want, of all sizes and shapes, and still nothing gets broken
Putting on a show – you don’t need a barn, or talent
Raising children – you can have all the good times and none of the bad, but don’t do this if there really are children around, as they might not understand and you’ll hear a lot of “Mommy (or Daddy), I’m scared”
Learning a nonexistent language – again better without anyone around as speaking in tongues might scare others into thinking you’ve had a stroke
Throwing out the garbage – no need to really throw it out if you can’t smell anyway
Going for a walk – easier to keep your distance from other people when they aren’t really there
Having sex – no change here, it was always imaginary anyway
Writing a blog – if I’m imagining this, please call me, but not on my landline, it’s not working, except in my imagination
