Are these sentences natural? August 24

Hi,

Are the following sentences natural to a native ear?

1. Why are there no tricycles for men?

2. It was hard for me to keep my eyes open in the meeting. I was dozing off all the time.

3. We are already short of people.

Thanks,
MG.

They all seem fine to me, MG.
