When planning a water activity, it's best to include a friend or a group of friends rather than going alone, even if it's an easy activity. true or false?

True. You can never be too careful in the water. Particularly in free moving water like rivers and seas, sometimes the current can be stronger than you assume and you can get in serious danger. Even in still waters and manmade water activity centres like swimming pools, you can still get into difficulty, for example if you hit your head.
