- This was not a poll.

- Being common doesn't mean it's good or acceptable. In this case, it doesn't account for the effects of day of the week, or what sort of issues the person was having on that day specifically.

- n=258 is enough if it was sampled properly, and they provide no details to show that it was, so it wasn't. They provided nothing more than the engineers they surveyed were in the UK. Nothing on experience, age group distribution, family-size, years of work, company size, work change.

- As it stands, this provides 0 valuable information, and I can only assume it's intended for buzz.
