They have proven this apparently that some people have this naturally, which is why they can get away with doing almost anything. Others do not.

The nature of person's aging depends, of course, on genetics and environment (which includes lifesyle factors). But one environmental factor discussed here, tobacco smoking, is on its own highly rejuvenating, as all the hard science demonstates (it's all produced by antismoking scientists, as you can see from the cited papers). As explained above, the heavy social engineering against smoking has resulted in a shift of this factor toward underclass or people with poor genetics in any class, who need smoking as self-medication.

Hence, many smokers are of poor health and do look prematurely wrinkled despite of smoking not because of it -- they are smoking against all the social and economic pressures of our times to offset the best they can all the other factors, genetic and environmental, driving in the opposite direction (you realize how inhumane antismoking is -- it is in most cases no different than ripping an IV and breathing tubes from hospital patients because IV and breathing tubes are associated with reduced life-expectancy). In other words, the fact that smoking is helpful for skin and for general rejuvenation does not mean smokers will have better skin or be more youthful as they age, just as rise in temperature this Tuesday morning does not mean this one is warmer than the last Tuesday morning, when temperature decreased.

So for me the smoking does not work.

The benefits of smoking are in part due to the 'exercise effect' -- it is an aeorobics for immune and detox systems (also for nerotransmitter, endocrine, cardiovasculatory and metabolic systems/networks). But if a person has broken leg, running would not be good for him, even though it may be good otherwise. Starting younger is also a plus and smoking was traditionally started as a rite of passage in mid-teens, from ancient American Indians through modern times (as well as with people on those photos). Some cultures, such as Semai people of Malaysia, take this benefit of "younger" to the absolute extreme and start smoking at age two (and have no 'smoking related' diseases; e.g. all 12000+ Semai adults were medically examined in depth in 1970s and the astonished scientists could not find a single lung cancer).

There are also various forms of smoking. Pipe smoking, although not very common among women (see here), is the most gentle kind of smoking (and similarly, pipe smokers are the nicest people you will meet).
