Losing my mental acuity. That's the worst, hopefully death comes before that happens.

I'm not sure whether this is a phobia or just an irrational fear, but I'm afraid of growing old. I'm 21, and I already have this kind of fear, it doesn't make sense at all. I'm not worrying about wrinkles or saggy skins, but I'm worrying about "I'm already really close to 30, and I won't be able to do many things as an 'old' people. I can't walk fast. How about my health condition? And etc.". At this point in my life, I feel like I only have a little time left, time is ticking fast, and I'm racing against time.

In my region of Scotland, we have always celebrated Halloween, as well as many people continuing to speak a Celtic language. I kind of fear losing our Pagan nonsense and other traditions that make us a bit special. :)

On a more personal note, I am unreasonably frightened of family and friends becoming seriously ill. It's like extended hypochondria; any sniff or headache or other minor symptom observed in a someone I care about makes me worried that they've got something dreadful.

Honestly I'm afraid of not being able to see all the super cool advances of society. Hopefully that doesnt sound TOO weird. I work at a place where discussions of future tech are the norm, I'll be damned if I dont find a way to see it all.

On a slightly more serious note : spiders, heights, and the occasional horror media will haunt me for weeks.
