Ugh. You just gave me flashbacks to a friend who let me try his water bed in college. SO motion sick. Beds should not do that. Beds should be flat and stable and the only motion when you lie on them should be from vertigo, and hopefully not too frequently.
We did a count of stress deflectors at the new house, and found 5. First is the massage chair. Second is the sauna (which hubby has been in multiple times already -- I have enough heat issues that I'm reticent). Third is the jet spa tub. Fourth is the pool. And fifth is just looking at nature, which surrounds us on three sides. Our stress levels have definitely gone down, even if driving is sometimes extremely stressful. (It's the rotary. Hubby doesn't like driving them in the US, and navigating it while driving on the other side of the road is a special nightmare for him. He has no idea who is merging where.)
