Is a scale a good way to track a persons progress ?

Yes, you take your original weight and subtract your newest weight.
example: i weighed myself yesterday and i was 200 pounds. today i weighed myself and i weigh 150.
we know how much i lost because i have old data to compare to it. i lost 50 pounds in one day.
this is just an example, not realistic weights lol.
hope this helps.

Hiv can be transmitted through oral sex. you can get hiv through vaginal fluid and semen. if you have an open sore or cut in or near your mouth and an you get the semen or vaginal fluid of an infected person in those cuts or sores, you can get hiv
