swimming
you would use reaction time at the start.
You would use meters.
Goggles
Probably freestyle or backstroke, they have the easiest techniques and it is easier to coordinate with. Breastroke and butterfly would be harder since u have to focus on the rhythm and coordination of the kick. :)
The most important part of your body in swimming would have to be your legs. In swimming you use your legs a lot and I am a swimmer and I do a lot of drills only using your feet or using a kickboard. So it would be your legs.
Babies can safely start swimming lessons around 6 months of age, when they have better head control and coordination.
the old swimming pool was in poor condition
yes
I would like for you to please remove the alligator from my swimming pool. Yes, there's an alligator in my swimming pool. I suppose the alligator mistook my swimming pool for the nearby pond.
It would be possible, but the positioning of the wings wuld make it difficult and the natural movements of the wing would make swimming a confusing and unpleasant affair. A dragon would much rather fly over a lake instead of swimming through it.
Meters.
