It is related that when Rav Shmuel Wosner zt’l reached the age of 101, someone asked him, ‘Rebbi, how did you merit to live so long?’
He answered, ‘I never got involved in a machlokes that was not relevant to me!’
A talmid chochom related, ‘I once was at a wedding together with Rav Wosner zt’l. Suddenly, we heard loud screams from one of the corners of the hall. The Gaon asked me what was going on and I said that some people were debating a certain machlokes. He told me, ‘If that’s true, I’m getting out of here now!’’
And so he did. He got up and left immediately.
