Insulin syringes may vary in the amount of space between the bottom line and the needle (dead space), so if you are mixing two types of insulin be sure to discuss any change in the model and brand of syringe you are using with your health care provider. Novolin R can be mixed with NPH insulin right before use. When you are mixing Novolin R insulin with NPH insulin, always draw the Novolin R (clear) insulin into the syringe first. Add together the doses (total number of units) of NPH and Novolin R that you need to inject.

It's like the myspace and facebook status thing. I'm not sure how old you have to be but i guess at least 13. It's safe for the most part, if you set your settings to protected so then only people you chose can see your updates, if you don't then everyone can see them. would say you can be any age to get a twitter account, it's a really cool way to keep in touch with friends and family, and to let others know how you are doing and what your up to.
