I will describe several high-precision experiments in nuclear beta decays motivated by searching for new physics. I will discuss the beta asymmetry and the time-reversal symmetry breaking correlation, D, in neutron beta decay; and the e-nu correlation in the decays of 32Ar (a purely vector decay) and 6He (a purely axial-vector decay). I will try to convey my enjoyment in desinging, producing, running and analyzing the data from these experiments.
