Some of the most common STDs include HPV, chlamydia, herpes, gonorrhea, and trichomoniasis. The four STDs that are incurable are HPV, HIV, herpes, and hepatitis. All of the others can be cured.
I disagree with the person suggesting that an average person can go 4 mph for 24 hours straight. I think average distance for an average person walking about 3.5 mph would be about 20-25 miles in a day. Then they are going to want to eat and rest.
An average person has a stride length of approximately 2.1 to 2.5 feet. That means that it takes over 2,000 steps to walk one mile; and 10,000 steps would be almost 5 miles. A sedentary person may only. average 1,000 to 3,000 steps a day and would benefit by slowly adding more steps each day until they reach 10,000.
