When you are in research behind your desk, are you using c=h=g=1?
I think this is common now. Everyone is doing it.
Is there anyone, who is not doing it?
And if, why?

I don't do it because keeping units in my calculations makes them easier for me to understand on a physical level (I either use MKS-SI units, or work on concepts independent of choice of units (as in quantum information theory)).
But then, the theory work I do is simple enough that there isn't enough savings to be worth it.
If I want to avoid hbar, I consider frequency and wavenumber instead of energy and momentum.

$c=1$ always (GeV is energy, mass and momentum), $\hbar=1$ sometimes (decay widths for short-living particles in MeV), $g=1$ never (doesn't help in experimental particle physics).

Currently, I don't but I will once I move to my next lab, where I will most likely work with the atomic units (in which $\hbar=1$). Honestly, I don't like those inventions on unit since it makes comparison with the other result reported in papers in a different field of research indirect, and requires a calculator.
