To be fair their second and third are still decent albums, but when your debut is one of the best rock albums ever recorded there's really nowhere to go but down.

An undergraduate program is one you can complete without having already graduated with another university degree. This is the one you would go into right after graduating high school.

A graduate program normally has a university degree as an entry requirement, although some also allow practical experience (Masters of Business Administration [MBA] programs often allow applications from people who have worked in business for several years). Either way you would not apply to one of these programs right out of high school.

They're designed for the vertical speed you pick up falling off a bike, not really for moving collisions or collisions with moving objects. They're better than nothing, but you would need a much more robust helmet to protect you from the sorts of injuries sustained in motor vehicle collisions.

They're designed to protect against different injuries more common to each of the activities.

Bike helmets are generally designed to protect against low-speed blunt collisions (I've read about 4m/s), such as falling off your bike and hitting your head on the ground, or a small inclined object like a curb. They're also designed so that if you do hit your head your spine won't rotate, which can cause very serious injury or even instant death.

I know less about ski helmets, but they have to protect against higher-speed collisions with upright stationary objects (such as trees), and they also protect the user's face and eyes from cold weather while maintaining visibility, which bike helmets don't have to do.

Same. I was instructed to do exactly this by the hospital I was working in at the time, including dropping the towel on the floor if no receptacle is provided. Better to make a mess in one place in the washroom than spread germs all over the facility.
