I was thinking that as far as I know, an atomic clock, and a mechanical clock, or a tuning fork clock might be affected differently by gravitation and acceleration. Is there any experimental verification of this? I'm trying to figure out if atoms will decay faster and that is it. Or if, your body ages faster all together, but your mind is the same age. Or, if your mind, body and atoms all slow down together? Are other forces affected by gravity, for example, covalent bonds? Magnetism?
