One man in our local group hadthe problem of falling very often--he was still playing golf a lot, and would accelerate in speed and crash, as your father did. The acceleration seems to be a typical PD habit, and often leads to falling. This may be different in cause from the kind of fall Peter had a year or so ago,when he suddenly went down and hit his face on the cub, breaking glasses, cutting head, etc. He had NO warning--I was right beside him, and the doc said it was probably due to a sudden drop in his already marginally low blood pressure. No acceleration inhis case. Camilla Flintermann,CG for Peter 76/6+ Oxford,OH <[log in to unmask]>
