A thing that happens to me that I ponder the occurance in others

I think I've forgotten how to walk up stairs.

Upon the last couple of stairs in the set it quite often happens that I completely forget both how to walk and the order of the next moments.

This tends to occur most when:

• carrying a full till of money
• with a drink in my hand
• on the way to the shower

I think I am perhaps reversing my evolutionary process.

I can however carry an unnatural amount of glassware. pros and cons.
