View source for Reb Itche der Masmid

''R' Itche der Masmid'' used to stay by my grandparents in Charkov in Soviet Russia. 

My grandmother's mother, Bubbe Rochel Leah, was old and frail and she lived with my grandparents too, and would lay in bed in her room.

On day while while davening, R' Itche realized that everyone left, and he's alone at home with Bubbe Rochel Leah. It was a freezing day with subzero tempatures, and he was sick with a cold. But he did not hesitate and immediately left the house, and continue davening outside. 

When the family returned they asked R' Itche, Why did you leave? It was only a weak old lady ("''alte yidene''") laying in bed, and you're sick with the cold... what problem could there be? Plus the freezing temperature outside is really dangerous!

R' Itche replied: "The Yetzer Hara is such a Mumche that he could make her young, and make me healthy!".
