Why common sense is not common?

This equation made me understand why grandma and most people are reluctant to do what most people think is healthy,
namely exercise, eat healthy foods.
More importantly, why we chasing after the latest drugs like Ozempic GLP-1 and bariatric surgery?

Example in this case your dream outcome is losing weight and become thin, the value of the solution increase by ⬇️time delay and ⬇️effort & sacrifice, and your own perceived likelihood of achievement.

Imagine a pod that can transform your body into your dream outcome,
it instantly makes you perfect body shape with 0 time delay, 0 efforts required, 0 side effects, no doubt it will worth billions💸🤑💰, Captain America transformation anyone?

Let's look at common sense

Exercise

You're sweating and tired🥵,
your muscle sore😫,
and you not see the results you want after your workout,
⬆️effort and sacrifice is through the roof,
⬆️time delay,
⬇️perceived likelihood of achievement,
so it must be low value,
you brain goes "Oh this sucks! Don't try to do this again! "

Healthy meals

You're want to eat carrot, leafy greens, sweet potato while surrounded with chips, doughnut, pizza, fried chicken, and you go "Mehh... leave lose weight part to tomorrow, what's the big deal? Life is short, let's enjoy it now."

Sleep

You know sleep affect your next day
but sh*t this show is so exciting just one more episode,
oh come on just one more round of battle royale,
it's still early what else on my social media feeds,
oh boy it feels good to be high and drunk,
still got work to do, emails to reply to...
