Glad to hear you are oK, I had a mild stroke 5 1/2 years while I was playing golf. Thankfully, my golf partner was on the ball and took me to the local fire station and they zipped me off to the ER. After 3 days in the hospital and many tests, they released me calling the incident a TIA. I have been on blood thinners ever since and will be for the rest of my life so I am told. The incident was definitely an eye-opener. I was diagnosed with diabetes at the same time, so I have to deal with that too. Take care of yourself and get regular checkups. The riding mower is a great idea.
