    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.
