Well exactly. Re what @SmartDog said about how 'everyone has got time to walk 3 hours a day they just CBA.' Most people do not have the time. Maybe some people DO have the time, but they can't do it every day. Not because they don't 'have the time,' (some people will do some days) but a 3 hour walk, (around 9-10 miles) every single day would become time consuming and quite tedious. And I say this as someone who enjoys walking, and goes for a walk of 1.5 to 2.5 miles, 5 or 6 days a week.
Even if you live in the countryside like I do, there's only so much of the woods, country lanes, canal, fields, and river that you can bloody look at. If you live in a town or city it's not much fun trying to get 10 miles of walking in at any time.
And who the F is going to walk to do their weekly food shop?! How the hell are you supposed to carry it?!
I can't even carry mine from the store to the car, and have to use the trolley! Unless you have just a small carrier bag full that you can stick in a backpack, walking to do your food shop is untenable. And it's ludicrous to suggest anyone does that.
And not everyone can 'walk to work.' For a start, around half the working population work half an hour's DRIVE - or more from where they live. To walk that, it would take 5 HOURS. (10 hour round trip walk LOL!) Plus people have to take children to school, and then go to work (and some schools are not 5-10 minutes walk from where the family lives, and then you have the work commute on top.) So walking to work after dropping the DC off at school is not gonna work for many. And if you work half hour's drive away, or more (like around half the population of the UK) it will be impossible... Are you going to drop your DC off at 4am?! So you can make it to work for 9am?
And what if it's raining, snowing, very cold, or very hot, is not doable for many people, especially as I said those who live half hour drive - or more from their workplace. If you DID walk, (if it was a reasonable walking distance, like 45 minutes walk,) most of the time, you would be soaking wet from the rain, or from sweat. (Or both.) OR windswept! Who the F wants to work in THAT state all day? And who wants to work near someone who's walked maybe 3-4 miles to work?! And as I said, how will you do it if you have to drop off children at 8.30-8.45am, and your work starts at 9am? (And your work is 3-4+ miles away..)
Some truly daft and ludicrous posts on this thread from (some) posters who clearly don't live in the real world!
Far better to set a small walking goal - like 1.5 miles (around 4000 - 4500 steps.) Much easier to do. And you're more likely to stick to it. NO-ONE is doing 10 miles walking a day LOL! (Waits for the usual predictable 'I walk 10 miles a day, every day, doing my job claims. )🙄(No you don't!)
