In Finishing the sentence LVI, I posted the responses I received to this sentence in 1988. Here are responses I obtained when I reran it in 1993:
The key to a stress-free life is...
...trusting in God. (Chad A.)
...complete unawareness of your surroundings. (Liz F.)
...to become a pampered house pet. (Molly H.)
...not to have one at all. (Paris A.)
...to remember that you are not intrinsically bound to any career, lifestyle, place, or person. If one's situation becomes too stressful, one should always remember that steps can be taken to change or leave that situation. (Jennifer D.)
...listen to blues very much, eat SpaghettiOs at least once a week, sing in the shower, taste a buttercup, pet the stray cats, have a beer, and put your feet up. (Karen B.)
...death? No, seriously, when someone finds the key, can I make a copy at the local hardware shop? (Rachel N.)
