Can a blind person ride a horse?

It really depends on the individual horse. Some never adjust while others seem not to notice much at all. I have been to horse shows and have competed against one-eyed horses. And horses that have lost all sight can live long, happy lives if kept in a small enclosure. Many owners of blind horses will put a companion horse with the blind one as a 'seeing-eye horse.

How does technology help people?

It helps us advance in knowledge setting us above apes and other animals it has excelled us in the practice of medicine and has helped us reach the moon but it has also let people become obese and lazy and has also helped to keep people alive when they should be dead because they are put on life support and that is just cruel to keep someone alive when they are ready to go just for your own feelings.

What would cause water to seep out from under the toilet bowl onto the floor when the toilet is flushed?

2 things. Thing 1 - you have a partial clog somewhere in your pipes, this is why the water is backing up in the first place. Thing 2 - the wax seal under the bottom of your toilet (you can't see it because its UNDER the toilet) is broken. Buy a new one at home depot and install (very easy, I've done it before without any prior knowledge) AFTER you have the clog removed. Try sticking a water hose as deep as possible into your outside tap leading to your plumbing - then turn it on full blast. This works for me every 8 months (stupid dry texas!). if the lines are not clogged, you need a new wax ring I had a problem similar to this. I changed the wax ring several times, but after a couple of months it would happen again. I snaked it myself a few times, but the problem came back a couple months later. Had Roto-Rooter out, but the problem came back a couple months later. I installed a brand new toilet (with wax ring), but the problem still came back. The best advice I can give is to get something that will prevent roots from coming back into the main sewer drain. Roots always seemed to be the one thing I could pull out of the drain when I snaked it.

How do blind people use websites?

Access technology such as Freedom Scientific's JAWS for Windows screen reading software enable the blind to use mainstream computer applications. Most legally blind people (70% of them across all ages, according to the Seattle Lighthouse for the Blind) do not use computers. Only a small fraction of this population, when compared to the sighted community, have Internet access. This bleak outlook is changing, however, as availability of assistive technology increases, accompanied by concerted efforts to ensure the accessibility of information technology to all potential users, including the blind. Linux distributions (as Live CDs) for the blind include Oralux and Adriane Knoppix, the latter developed in part by Adriane Knopper who has a visual impairment. The Macintosh OS also comes with a built-in screen reader, called VoiceOver. The movement towards greater web accessibility is opening a far wider number of websites to adaptive technology, making the web a more inviting place for visually impaired surfers. Experimental approaches in sensory substitution are beginning to provide access to arbitrary live views from a camera.

Does hydrochlorothiazide cause hyperglycemia?

The connection between diuretics and hyperglycemia involves intracellular K+ levels. Intracellular K+ is involved in the secretion of a lot of hormones...including insulin. Some diuretics cause hypokalemia, (decrease in K+). This inhibits insulin secretion and can lead to hyperglycemia. It's not really a problem unless the patient is pre-diabetic. In that case, it is significant enough to push them over to diabetes. Hope this helped!

What are the difficulties faced by the visually handicapped people?

We have a good amount of difficulties but I'll highlight a few Lack of transportation especially in small towns. If buses aren't clear with stops and numbers we're not going to get around easy, and highways aren't good for us at all. Employment: Up until recently I didn't know what I'd do for a job because we aren't really able to just go work at mdonalds like sighted people. Being a cashier or teller isn't our first option and so many employers are so SCARED to hire visually impaired people but thanks to ticket to work program things can get better and the VR services in GA are good but here in Charlotte they are terrible. We have to struggle but it's worth it. Socializing: I'm 22 so maybe people older than me don't care but I really feel like if my eyes didn't look funny I'd approach people more. People still approach me but I get nervous thinking they'll pick on me. Most of my teasing oldly came froma dults when I was younger. We work better in big cities like ATL where people are more diverse and open minded about disabilities. If you're talking or approaching a visually impaired person you know say their name then say hello or whatever so we know you're talking to us because so often we can't make out your face let alone where your eyes are looking. Housing: okay I'm thinking of moving so this one is close to me. If we don't work from home we have to make sure a bus stop or our place of employment and grocery stores are near our area. We also have to make sure it's safe due to the fact that many visually impaired people walk. Some jerk landlords try to discriminate because they think we're a liability instead of looking at our ABILITIES. Heck most visually impaired people are cleaner and quieter than sighted because we care for others and pay attention to detail.
