Sports and Recreation
It is a funny article. Read this quite carefully:
I do like riding bicycles. I like riding them to the shop to buy a newspaper, then riding them home to read it, preferably in bed. In summer, I sometimes even ride my bike to work. Often, if the following summer is nice, I’ll ride it home.

There’s nothing technically wrong with an octogenarian strapping on tanks and descending to the ocean floor, but most people wouldn’t consider scuba diving at such an advanced age.
Then again, Ray McAllister is not your average 84-year-old.
So even with my impending birthday, I’m still not too old.
This was last week at Arifjon where we were mapping the wreck as part of the Divemaster course. The visibility was very good most of the time and there wasn’t too much current over the wreck. As it can be challenging carrying a slate and tape measure.
I generally do frog kick with the big fins on. I find it more relaxing…
Picture #2, a swimmer with 40 degrees will have a kick that is of little or no use. To place the top of the foot at an angle that is propulsive requires significant bending of the knee. When the knee bends, the thigh moves down and causes enough drag to cancel out most or all of the propulsion from the top of the foot. The kick is not worth doing. These swimmers love pull buoys! Swimmers with less than this range of motion, when kicking flutter kick on a kick board, can actually go backwards.
This is why I am so slow in the water, compounded by heavy muscular legs.
Well there is the possibility of using the rack to improve my flexibility. I think I can build one of them myself.
The Kick
Well not yet, but I’m taking the course now. In PADI’s words:
What can PADI Divemasters do?
- Work at local dive centers, on live-aboard dive boats, yachts and at exotic resort locations
- Assist PADI Instructors with students
- Lead PADI Scuba Divers on guided dive tours
- Teach and certify PADI Skin Divers
- Teach PADI Discover Snorkeling programs
- Conduct PADI Scuba Review programs for certified divers
- Lead certified divers on Discover Local Diving experiences
- Teach Emergency First Response programs after successful completion of an Emergency First Response Instructor course.
It will be a challenge as there are some skills to really hone up on (more…)
