Moving on to the next thought- why are you having second thoughts on having junk food? Of course every doctor, nutritionist or a gym instructor advises against it, to state the obvious- it deteriorate your health. But it is so tasty and it never fails to tickle the taste buds to glory.
Humans are an ever evolving species, and thankfully their brains have finally evolved into, colloquially speaking, far advanced version of what it used to be. Thus now capable of coping with the 'junk food' syndrome. Though slowly, but people are indeed taking the ball to the 'healthy' side of the court.
And by bored it means they:
1) have healthier things to eat,
2) want to avoid obesity or any other direct/indirect adversities of junk food, and
3) are now allured by gourmet and organic edibles.
"Whoever snuck in the 's' in 'fast food' was a clever little prick."
Now it is to be observed where this trend takes the fast food industry-- the repercussions can be multilateral and multifaceted. Either this trend is ephemeral and would subside with time or the shift in paradigm would sustain all through the generations to come.
