The world is becoming less accommodating to ND people, so our lives are becoming more challenging.
Examples:
Loud noise and music everywhere.
Lights are brighter.
Hyper social activity is encouraged - eg social media.
People are more likely to voice their opinions now and seem louder and more outspoken. There seems to be more bullying now.
The workplace is more complex and competitive.
Extroversion is more highly valued now more than ever.
Technology is more varied and complex.
Systems are more bureaucratic.
People are more likely to take offence.
More traffic, people, buildings etc.
More novelty on a day to day basis like a pp mentioned - non uniform days in school. Also, social team building exercises in the workplace.
Life is faster paced.
It's difficult to earn enough money to get somewhere to live now.
All these things and probably more are putting pressure on ND people and we find it harder to conceal our difficulties.
