I saw yesterday on TV that an inventor presented an airbag for handicapped people. I thought it could be useful one day for PSP people.
After a bit more thought I wondered if a permanent thick protection (in particular for the back) associated with a helmet would not provide enough protection to PSP sufferers to let them move as they wish. As long as they do not brake too many things in the appartements when they fall. Last fall of my wife, she broke a small table, a spendid lamp on it and the telephone. But herself; nothing!
