Too much time spent devoted to pointless subjects (PD/H/PE) and not enough on maths and science.

Hmmm

what is pointless depends on your point of view

So much obesity- people smoke and get drunk- our population needs to learn how to exercise I reckon

Stand up. Place one foot in front of the other. Repeat. Increase rate of foot placing for greater results.

Hmmm... not exactly rocket science, is it? Maybe we could teach kids simple things like that in primary school, so that when they're in high school they have more time to devote to subjects more interesting and enjoyable than chasing a ball around a paddock for no damn reason.

A national Service is the best start for improving mental & physical fitness.

Surely the really vital messages must be transmitted by families. Eat a sensible diet; get sufficient exercise and get your body moving every day; don't fill up your lungs with yucky smoke; drink in moderation and sensibly; have some special friends and family and take care of them; read widely and consider other viewpoints and ideas as well as yours.

This might keep you as strong and healthy and wise as you can manage. School really just fines-tunes what you get at home.

Why only yesterday my son told his daughter: "Have good manners please.That means- not tipping food on your head". Mis Bossy-boots is 2. Never too young to learn!

You've obviously never had any exposure to blue collar workers' daily routine.
Healthy food is unaffordable for 30% of the population & exercise is something only those overpaid & underworked public servants have the energy to do.
What's needed is a cut to public service pays so that at least some equality can be established which then will boost the economy due to a more balanced spending power.
