Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.o, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood. Genes are the basic unit of genetics. Human beings have 20,000 to 25,000 genes. These genes account for only about 3 per cent of our DNA.
I usually get my hair cut in a small-town shop. I tip $2 on a $12 haircut. If I get to hear stories about Vietnam or histrionic political rants, I tip $3, even if I donât agree with the barberâs viewpoints. (I tip because Iâve been entertained.) Sometimes, if I donât have enough cash, I donât leave a anything at all.
PayScale also found that there's a gender gap for tipping, with men being tipped less than women. In PayScale's sample, women earned $1 more per hour in tips, but men were paid $1 more in base payâbringing both to about $13 for median pay per hour.That's still below the national median for hourly wage for all occupations, which is $16.87, but it's $4 more than the BLS median for waiters and waitresses.or example, Payscale's top median tip earners were bartenders in San Francisco, who reported earning a median of $15.50 in tips per hour. For bartenders, the worst place to be is New York, where the median amount earned from tips per hour is $7.10.
