A hug
This is a picture from an article called "The Rescue Hug".
The article details the first week of a set of twins.
Apparently, each were in their respective incubators,
and one was not expected to live.
A hospital nurse fought against the hospital rules
and placed the babies in one incubator.

When they were placed together, the healthier of the twins
reached out an arm over the sister in an endearing embrace.
The smaller baby's heart stabilized and her temperature rose to normal.

Let us not forget to embrace those whom we love.
