  Here we present an approach to the measurement of extragalactic distances
using twin SNe Ia, taken from the early down to the nebular phase. The approach
is purely empirical, although we can give a theoretical background on why the
method is reliable. Studying those twins in galaxies where peculiar velocities
are relatively unimportant, we can tackle the H$_{0}$ tension problem. Here we
apply the method to the determination of the distances to NGC 7250 and NGC
2525, who hosted respectively SN 2013dy and SN 2018gv, twins of two different
SNe Ia prototypes: SN 2013aa/ SN 2017cbv and SN2011fe. From the study of the SN
2013aa and SN 2017cbv twin pair, by comparing it with SN 2011fe and applying
the difference between the SN 2013aa/2017cbv and the SN 2011fe class, we find
as well a good estimate of the distance to NGC 5643. We just have started to
measure distances with this method for the samples in Freedman et al. (2019)
and Riess et al. (2022). There are differences in measured distances to the
same galaxy using Cepheids or TRGBs. In this context of discrepancy, the "twins
for life" method is very competitive, as it can provide distance estimates with
a modulus error of $\sigma_{\mu}$ $=$ 0.04 mag. Our findings call for a
revision of the distance measured with Cepheids in Riess et al. (2022). NGC
7250 and NGC 2525 need better measurements with Cepheids. The Hubble tension
can arise from the way in which the local SNe Ia sample is linked to the SNe Ia
Hubble flow sample. A good calibration of distances of SNe Ia in the local
sample can be provided with this approach. We aim at comparing them with SNe Ia
twins in galaxies at z $>$0.02--0.03 well into the Hubble flow to obtain a
reliable value for H$_{0}$.
