Sorry to hear, and hope for a good recovery.
I have heard that heart attacks are an occupational hazard when working in the real estate biz due to the nature of the job. Long hours being sedentary at a desk, talking on the phone, talking in-person to clients and then driving out to properties for a look-see with little to no physical exercise..
Could be that trading in their Lexus' for a bicycle built-for-two, and then peddlng out to view properties could be good conditioning for both the broker and client.
...ok...start slamming me for poorly timed comments, I can take it.....
