Things you are unable to do or that are really difficult

For me its always driving any kind of vehicle ...also stairs are my natural enemies.

For vehicles , simply,  any kind of control , whether its the steering , pedals or whatnot , they all start to feel like mush and I always end up crashing.

As for stairs , any next step is visually there but not physically , thus I step into nothing , I realise that I am falling/tripping and wake up violently.

Stairs are pretty rude ..
