Speed in itself is not that dangerous, inappropriate speed is. Always take into account the weather and road conditions. Driving at 60mph, even though you are legally entitled to do so, when there is ice on the road is dangerous and inappropriate, as is driving at 40mph on a dual carriageway when the weather is fine. The general speed limit rules for cars are:
Adult bed bugs can survive a full year without feeding, going into a semi hibernation state until activated by the CO2 from a blood source. Normal life cycle for a bed bug is up to a year and a half, while younger bed bugs can go about a month or two without a blood source before dying.
The question of how long you can go without food depends on a lot of factors. Will and determination definitely play a part. Political prisoners on hunger strikes and fasting religious leaders have been known to go for weeks at a time without any food. Gandhi fasted for 21 days while in his 70s. People lost in the wild have also survived for long periods of time without eating. Medically speaking, most doctors agree that healthy humans can go up to eight weeks without food as long as they have water. People have gone longer and been fine, and people have starved to death in less time. Being strong and in good physical shape can help you survive longer, but so does having extra body fat.
