What are things best not done while drinking?

ASIDE OF DRIVING- what are things best not done while drinking?

This question was inspired by another thread that went astray.

@evelyns_pet_zebra mentioned that drinking and welding might not be a good combination.

My response was that trimming hedges was not advisable to do while drinking.

What other activities might be a disaster if done while drinking?

This does not need to be a personal experience story but if it is all the better!
