Gravity can be replecated in the kitchen sink when things that are floating in dirty water are attracted to a glass sitting in the soapy dirty pot.

I believe gravity is created by the displacement of space.

Water is an excellent medium. Has interesting properties(from Chemistry point) unlike any other compund. Let's not forget our body's 2/3rd content is water only.

SPA stands for Salus per Aquam. Water relaxes the body as well as the mind. But it will not build bone mass or bone strength. Water buoyancy will facilitate a person in trying a range of stretching motions in water.

Some exercise is better than no exercise at all. Don't give arthritis as an excuse not to do some light weights. Depending on your condition, start with 1 lb dumbbell. My cousin sister suffers from RA. Her condtion is worse. I tell her the samething. Initially it will be painful. There is always the "inertia". The reason I am telling you this is I used to do lot of really "flexible exercise" when I was in my teens and early twenties. My back would be very flexible. But for a decade I stopped some of those exercises but continued with my regular push-ups,walking/running, some crunches. Again I have started pushing myself doing some stretching exercises. I think "oh my god, how my body is used to bend but not anymore". But I'm improving. It's not easy for even a person who has been athletic.

I would prescribe "40-50 mnt exercise daily" for women(applies to men too) especially past 35 yrs. As we grow older, our metabolism slows down and the only way to keep ourselves healthy and fit is by doing exercise daily. There is no other short cut.

My cousin, has Juvenile RA, while talking to us, all of a sudden her shoulder joint got dislocated and her right arm was hanging loose. Everybody was panicking but not me. Because my father knows a lot about medicine and has taught us some emergency tricks. I immediately got some oil and started giving her a massage and the arm, after couple of circulatory motions, got clicked at the right spot and my cousin sis, screams "stop". Before even my other relatives tried calling the ambulance this oil massage worked out!

Finally, don't stop the water exercise. It will relax your muscles. But wrt bones, start thinking about walking(choose a path that has some elevation,that way you put slight stress on your knee) atleast 20mnts daily, give some oil massage for the joints. If there is no blood circulation, the joints become stiff. Oil massage(any oil will do as oil is a lubricant, makes the flow smooth) works great. Try it. Hot packs(water), cold packs(ice) also improve the flow in and around the joints.

With small kids, you can do this exercise. This is good for the lower half. I do this with kids under 8-9 yrs(depends on their weight). I sit on a chair and stretch my legs and tell the kid to stand on my feet. I will hold the kid's hands(so that the kid doesn't fall) when I lift my legs up and down.

In everyday life, if I gain more weight then I will experience more of the effects of gravity on my skeletal frame, and this can actually be good for me?

The type of gravity best used for exercise is usually found closer to the ground.

Do not assume that increasing your axial load by overeating is beneficial.

Does aqua-aerobics count as axial load exercise? Because of arthritis, the use of dumbbells and and bench press can be very painful. I do use small floatation dumbbells and water weights during my aqua-aerobic routine though.

I think humans were to flourish on earth. But outer-space does sound like a fascinating place....maybe on a short-term basis.
