A new study by university researchers supports the stereotype that gay men
are thinner than straight people and lesbians are heavier.The report,
published in the American Journal of Public Health, looked at a survey of
more than 67,000 Massachusetts residents between the ages of 18 and 64.
According to msnbc.com, researchers found that while 21 per cent of straight
men were classed as obese, only 14 per cent of gay men were.Conversely,
they found that 26 per cent of lesbians were obese, compared

Thank you all for the insights. Then, will use a different material (lighter

This is an excellent longrange cartridge, but it derives it's performance
from a couple very specific longrange bullets.
It's good to 1000yds, but the wind will be pushing the lighter bullets
around much past that.
The realistic maximum range is 1500yds with 115gr Dtacs.
There are no factory made rifles so this is a custom build proposition.

All other things being equal, occupants in a bigger, heavier vehicle are

Size and weight affect injury likelihood in all kinds of crashes. In a
collision involving two vehicles that differ in size and weight, the people
in the smaller, lighter vehicle will be at a disadvantage. The bigger,
heavier vehicle will push the smaller, lighter one backward during the
impact. This means there will be less force on the occupants of the heavier
vehicle and more on the people in the lighter vehicle. Greater force means
greater risk, so the likelihood of injury goes up in the sma... 阅读全帖

Small/light vehicles have less structure and size to absorb crash energy,
so crash forces on occupants will be higher. People in lighter vehicles are
at a disadvantage in collisions with heavier vehicles. Pickups and SUVs are
proportionally more likely than cars to be in fatal single-vehicle crashes,
especially rollovers. However, pickups and SUVs generally are heavier than
cars, so occupant deaths in SUVs and pickups are less likely to occur in
multiple-vehicle crashes.
