Nerve agents and substances causing injury to the skin and tissue are easily soluble in, and penetrate many different types of material, which renders decontamination more difficult. If chemical warfare (CW) agents have penetrated sufficiently deep, then toxic gases can be released from the material for long periods.
To be a jockey, there are no height limits, only weight limits. A rider can be of any height if they can still make weight, but it is still generally limited to fairly short individuals because of the limits on a person's body. Jockeys typically range from 5' to 5'7 in height. No need to lose any weight.
there is no specific weight but you wouldn't want to be very heavy but you should be well under 200 id say 150 is a good weight but lower is good. This is wrong. To become a jockey the average weight is 100-108, in the Kentucky Derby the weight limit is 126 pounds with gear. The average weight without gear is 100-108, with gear is about 120ish.
