Most of us are thankful we can see the world around us.
So the notion that we might be plunged into darkness is one of the more common fears. But it happens to many people.
North East Sensory Services is working hard to break down barriers and educate the uninformed about the realities of blindness.
That helps explain why they are holding a unique event on Friday, June 12 at Cafe Coast in Aberdeen.
Dine in the Dark will enable participants to enjoy a new sensory experience – by enjoying a fine meal without sight.
The guests will be blindfolded and discover how their other senses work harder to enable them to enjoy textures, smells and tastes.
The event will be hosted by blind comedian, Neil Skene, who is one of life's inspirational figures.
He has climbed Kilimanjaro, travelled to base camp at Everest, run marathons and appeared at the Edinburgh Fringe.
As he told me: "The important thing is NESS are very positive about disability and there is no sense of allowing people to feel sorry for themselves.
"Yes, being blind or deaf is frustrating, but, in most cases, it is not life-threatening.
"I think the last thing people such as myself want is for others to say things like "Poor you" and act as if we can't do anything positive."
With that attitude, it's hardly surprising Skene is in favour of such ideas as "Dine in the Dark".
It’s a popular concept enjoyed world-wide, and tickets are on sale from Café Coast at 01224 594488.
All proceeds to go North East Sensory Services, which has been supporting blind and hearing impaired people in Aberdeen since 1879.
