Completely agree with the previous 8-9 people who posted after your weird post! Yours is the most batshit post on the thread. (Probably the most batshit on Mumsnet this month so far!) 'Grown women walking with backpacks is odd,' because 'only teenagers' do this? And 'walking everywhere beyond your early 20s is unusual?' Also, as a pp said, where on earth do you live where 'no-one walks anywhere' and anyone walking anywhere, would be stared at - and looked upon as an oddity?!
It's really not unusual for people to walk instead of driving sometimes. I know MANY people of all ages, right up to their 80s, who walk regularly. Particularly where I live as it's a beautiful, rural area. There is a big walking group that do 3-5 miles walks, on Wednesday and Sunday mornings. Mostly in their 50s, 60s, and 70s. But a few younger, and a few older too. (Maybe 50-70 people altogether.) AND THEY HAVE BACKPACKS TOO! AND THEY ARE NOT TEENAGERS!!!!!! 😱 I also know a number of people - actual grown adults! -who walk to work and back! (A few of them have backpacks too. OMG!!!!!) 
Your post is so ignorant. Educate yourself.

Walking is really good for you. It's good for your heart, good for your respiratory system, and good for your soul, and it's an extremely healthy thing to do. It builds stamina, and muscle, it can improve the quality of your sleep, and it increases your heart rate and blood flow, and it helps bone health
Walking is a weight-bearing activity that can increase bone strength and slows the process of osteoporosis. It can also improve your mood and reduce your risk of depression .. Walking releases endorphins, dopamine, and serotonin, which can make you feel happy and positive
Walking can also reduce stress, and build your immunity ... Brisk walking can help your body produce more immune cells, which can help fight off infections.
Also, walking increases blood flow, which can help you feel more alert and refreshed. Other benefits ... It can also improve your memory and reduce your risk of dementia.
Finally, Walking can help you prevent weight gain.
Your posts is bonkers. 😆 Sounds like you're projecting, because you drive everywhere, (probably even to the corner shop 100 feet from your house, and to your kids school 5 minutes walk away!) and you can't fathom why anyone would want to walk ANYwhere.
Also, I haven't seen anyone say they walk everywhere all the time. Just a number of posters saying they enjoy walking, and prefer to walk rather than get lifts most of the time. They're not walking everywhere. Like when I go to the beach - 40+ miles away, I am not walking there. Nor am I walking to my nearest city - 12-13 miles away! And I don't walk to my local market town to do the food shopping, as it's 3.5 miles away, and I wouldn't be able to carry all my shopping back 3.5 miles!
Seriously, I am wondering if you're that batshit woman who wanted me to get in her car, for the last 7-8 minutes walk to the Christmas fayre, and started laying into me in front of people for not accepting her lift when she saw me there. Throwing her toys out of her pram, and spitting her dummy out, because someone had the temerity to not do what she demanded! 😂
I'm embarrassed for you @CantStopBuyingSeeds !
