It is, after a proper introduction to the water. I still remember when I went to the YMCA to learn to swim as a kid, some other kid in the 'class thing' decided to essentially try and drown me by using himself to pull me down into the deep end. The lifeguard/teacher had to save my ass and got onto him.
Yeah that totally didn't put me off for a while. I did eventually figure out the basics on my own, and surpisingly I liked water levels in old games.
For additional context, he literally held onto me to purposely drag me down and since I wasn't expecting it I inhaled water. Great combo.
