why do the elderly detect air flow resistance later than the young?

If you mean breathing trouble and restriction to their air way, it's because of a few reasons. Reflexes slow over time as well as brain signals, this means that they realize it slightly later and react somewhat slower, adding up to a notable difference. Also, many senses begin to fade with age, taste is one of them. So, it makes for a reasonable assumption to think that other areas very close to the mouth (IE the throat) would begin losing some sensations or have a slowing in the process of expelling things.

It all has to do with altitude. The higher you are from the earth, the colder it gets. Air is also thinner.

A....Maybe because you are getting OLDER!\n\n\nDDDDDDDDDDDDDDDDDDDDDAAAAAAAAAAAA

They had that on an episode of Mythbusters.  The ball travelled less further because of the decrease in mass and no change in volume.  It was more susceptible to air resistance.

I believe it has something to do with the fact that, viruses such as pneumonia affect  the older (and very young) moreso than an adult in his/her prime because the immune system is weakened.  Either by age or because it is premature (as in with children)  As you grow older, your body weakens and is once again more susceptible to disease/sickness.

It helps them breath easier.  Actually most people in distress will put themselves in this position without being told by anyone.  It helps them take deeper more effective breaths.  I have seen asthmatic patients do it as well.

Well, older people still get it on, so to speak lol. My dad was 62 when I was born and there was a composer (can't remember his name) who fathered a child in his 70s. As much it is weird to think of an older person getting it on, it still happens!

Usually boys / men because they have a larger lung capacity (on average)

your heat balance(net of heat gain & heat loss)is being maintained at a level just below the 'set point'(set naturally in the brain).whenever the brain detects low temperature it reflexly initiates certain behavioural changes(eg.wearing extra clothing or using extra blankets as in your case)to conserve heat.\n\nthere are various means of heat gain(eg.metabolic rate) & heat loss(eg.loss to the environment).at your place,heat ioss to the environment would not be much.you may be going through less heat production(low basal metabolic rate)commonly due to decreased thyroid hormones.\n\nanother cause,if you are elderly,could be early,clinically yet insignificant,compensated heart failure.\n\nyou need to take thyroid function test & get yourself checked for functional status of the heart.\n\nif these tests are normal,serious causes are ruled out.\n\nlow thyroid hormones are easily treatable & early heart failure can also be taken care of medically.\n\ndo let me know what came out of it at my email dr.rajkumarsood@yahoo.com

Increase in peripheral resistance...

Older people have lived longer.  They have had more life experiences.  You know the saying, older and wiser.  Well, they probably have been through most what young people are going through.

I suppose you are reffering to the small digital scales. They have a device whos electrical resistance changes under pressure.

its great when  your young and have a lot of energy. but as you get older you eventually slow down. well most people do.

Likely for the same reason that the furniture shrinks as we get older - the growing itself is what does it.  \n\nAs we mature, we have longer and longer attention spans.  We are able to sit quietly and complete a time consuming task - where as when we were kids, we had short attention spans and so we would flit from activity to activity, getting to do many more things in the same amount of time.  I think that creates the illusion of time speeding up for us.

For the same reason the rest of the body deteriorates with age.  Just like a car deteriorates with age. etc etc... use ..missuse abuse and just wearing out.

Actually, that would depend on the amount and size of the obstructions.  When you restrict the flow of something then yes you increase the "speed" of the "something".  You can reach a point where the constriction will actually slow the "air" down.  The "air" going through the smaller constriction will be faster, however, there will be a smaller amount of "air" going through.  Don't know if that made any sense or not.  ?  *hugs* :)

Hotter air rises when it is hotter than the air around it because it  it is less dense.Vise versa for cold air.
