MDA is a man-made (synthetic) recreational drug noted for its stimulant and psychedelic properties that has been used since the 1960s as a clubbing and sex-enhancing substance, with some similarities to LSD and MDMA (ecstasy). Sought after effects.
The soaring temperatures that Las Vegas is experiencing this week could cause grief for pilots at other airports, because heat thins the air and makes it more difficult for aircraft to lift at take-off. To deal with that, pilots need to gain more momentum as they roll down the runway before reaching liftoff speed.
Re: Dangers of Heating Pads!!! I use a special heating pad that has a built in safety feature that turns the pad off in time before it can burn you. My favorite place to sit while using it on my back is in my recliner. I lean against it but it always turns off before it gets too hot although it does get nice and warm. use a special heating pad that has a built in safety feature that turns the pad off in time before it can burn you.
