You may spend your leisure time very differently in the future....

Swimming pools of the future may be anti-gravity pools in the middle of air!

The races will be risk free and might be gambled on.  They also might be the second most popular way to spend leisure time in the future.

The technology might be the most popular way to spend leisure time in the future because of all the new technology coming out these days.

Most of the sports of the future will be anti-gravity and won't be based on sports that we play now.

Computer games like chess will be formed into virtual games played in leisure time.
