I love to go swimming. Just propelling myself through the water with the coordinated strokes of my hands and pumps of my feet. 
I like swimming as well but I do not do it very often anymore these days with work and al
It can be hard to find time for. It is one of the top public activities. In some countries it is apart of school curriculum. 
That is interesting, it is a great life skill considering the earth is 70% water haha
Very true, and we are very buoyant, which is required to swim.
that is for sure, sometimes I feel like I cannot float though when my head is under water
Your buoyancy is dependent on several factors. Like the salinity and your body composition. 
oh that is interesting, I never knew I could sort of change that, you learn something new every day
